THE SAFETY ROOF ANCHOR
![](asset-2.png)
EXPLANATION
A fundamental concept in the use of
maintenance contractor supplied conven-
tional suspended access equipment such
as bosun’s chair, single work cage or
platform is that there must be two inde-
pendent means of support for each
worker using the equipment.
The first means of support is the access
equipment itself tied back to an anchor.
The second is usually provided by a sep-
arate fall arrest system consisting of a:
• full body harness;
• lanyard (with shock absorber);
• mechanical rope grabbing device;
• lifeline;
• lifeline anchor.
In addition, anchors, which are used for
tie-backs or for securing lifelines, are also
an effective, practical means for directly
securing a bosun’s chair with descent
control equipment, the most popular
method of window cleaning today (direct
rigging).
Bosun’s chair is the equipment of choice
among window cleaners. Pro-Bel safety
anchors (see photo at right) are used to
secure chair and separate lifeline.

All Buildings Require Roof Anchors
Extract From ANSI/IWCA I-14.1
Window Cleaning Safety Standard:
4.1.1 All buildings where window clean-
ing is performed that employ suspended
equipment shall be equipped with roof
anchorages or other approved devices
which will provide for the safe use of the
equipment in conformance with the pro-
visions of this Standard.
SAFETY & TIE-BACK ANCHORS
![](asset-3.png)
DESCRIPTION
Note: Pro-Bel tie-back/lifeline anchors
and direct rigging anchors are the same
and are used interchangeably.
Safety Anchor Types
There are literally dozens of Pro-Bel
safety anchor products available. Each
has been engineered to satisfy a particu-
lar job requirement. They can be catego-
rized as follows:
PB and PBE Series Wall Anchors
PB wall anchors are fabricated using a
patented stainless steel U-bar which is
detachable for ease of replacement, con-
crete forming and waterproofing. PBE
anchors are a more economical alterna-
tive to PB anchors and are used when
flashing or waterproofing is not a consid-
eration.
PBE Series Roof Anchors
PBE Series anchors have a non-detach-
able stainless steel U-bar and are flashed
using a spun aluminum flashing sealed at
the top with a heat-shrink rubber collar
flashing.
PB Series Roof Anchors
PB Series anchors, somewhat more
expensive than PBE Series anchors, are
fabricated using a patented stainless
steel U-bar and stainless steel cap flash-
ing which is detachable for ease of
replacement.
USE
ANSI/IWCA I-14.1 (3.9 Anchorages)
states that “Building owners and window
cleaning contractors shall not allow sus-
pended work to be performed unless it
has determinded that the building has
provided, identified and certified anchor-
ages complying with Section 9 or 10 for:
independent safety lines; tie-backs for
outriggers, parapet clamps and cornice
hooks; primary support anchorages for
powered and manual boatswain’s chairs;
primary support anchorages for rope
descent systems; horizontal (rope) lines
or lifelines; and wherever else required.” Pro-Bel roof anchor set into concrete pier
(PB70).
Pro-Bel PB type wall anchor in concrete
wall of rooftop mechanical room.
Pro-Bel wall anchor recessed in box flash-
ing (PB71S).
Pro-Bel PB type steel pier roof anchor with
detachable cap and aluminum flashing.
A-3

cealed with cut out core trimmed with
stainless steel band and tabs.
![](asset-4.png)
FEATURES
All corrosion resistant materials;
anchor components are stainless steel
and/or hot dipped galvanized steel.
Standards conformance; all anchors
comply with OSHA and ASME/ANSI/
IWCA safety requirements for window
cleaning, and various materials stan-
dards.
Installation flexibility; Pro-Bel safety
anchors are suited to a broad range of
building structures, including concrete,
structural steel or precast panels.
Securement methods include cast-in-
place, through bolts, bolt around, weld-
ing, or chemical epoxy fastening.
Engineer certified; OSHA and ANSI/
IWCA I-14.1 requires that safety anchor-
ing devices be designed by or under the
direction of a registered professional
engineer experienced in such design.
Pro-Bel safety anchors meet this criteria
and anchor performance is based on
data derived from testing and/or engi-
neering calculations. Anchors have been
tested to ensure fracture or detachment
does not occur with the application of a
5,000 lb (22.2 kN) load in any direction.
Compatible with roofing; Due to strin-
gent OSHA anchor placement require-
ments i.e. in line with the point of sus-
pension and free fall distance, anchors,
for the most part, must necessarily be
placed on the roof. An important consid-
eration in the design of Pro-Bel anchor
products is the need to maintain the long
term watertight integrity of the building.
Pro-Bel products are designed with a full
understanding of reliable flashing/sealing
techniques to satisfy any roof condition.
Where anchors are located in water-
proofed areas of a roof, a pier is normal-
ly provided to elevate the anchor above
the waterproofing. In the case of metal
pier anchors, the pier is supplied with the
anchor and a prefabricated flashing to
suit roof type as required. With concrete
pier anchors, the pier must be formed,
the anchor cast in, and the flashing fabri-
cated at the job site.
Sole responsibility; Pro-Bel provides
complete fall protection products/sys-
tems from concept to the supply and
installation of same, including annual
inspection.
Specific liability insurance; all Pro-Bel
davit installations automatically carry
$2,000,000.00 coverage against product/
system failure (over 4000 projects suc-
cessfully completed to date).
MATERIALS/FABRICATION

supporting rooftop AC chiller unit.
Minimum anchors; OSHA and ANSI/
IWCA I-14.1 requires that equipment tie-
backs be “installed at right angles to the
face of the building whenever possible”.
This requirement, can result in an
unnecessary number of installed
anchors. Pro-Bel has developed anchor
placement chart data to help designers
locate anchors to suit tie-back and life-
line requirements. This data ensures
compliance with OSHA fall protection
criteria while reducing the number of
anchors (and roof penetrations) required.

Note Re: Alternative Finish to Galvanizing. For all anchor bases and supports, Pro-Bel offer a superior protective coating _Protex _in
lieu of galvanizing if desired. Pro-Bel Protex is a 3/32” (2.4 mm) thickness, black colored, two component spray on, flexible 100% solids ther-
moplastic (TPU) polyurethane/polyurea system. Protex provides exceptional impact and abrasion resistance and is factory applied via high
pressure impingement mix polyurethane dispensing equipment. See Pro-Bel Protex Technical Data Sheet # R-2 for complete information.

TESTING*
Testing of Pro-Bel wall and roof anchors
involve a variety of both shop and on-site
test methods including static, dynamic and
destructive procedures. All testing is car-
ried out by independent testing agencies
or under the direction of a professional
engineer in accordance with recognized
standards.
Anchors secured using epoxy adhesive
are tested to 5000 lbs (22.2 kN) to ensure
against failure. The photos on this page
provide an overview of Pro-Bel test pro-
cedures.
* Test data available upon request.
The static load test in the above photo, which applies force using a heavy duty cable
come-along, was conducted to show that Pro-Bel wall and roof anchors comply with stan-
dards that require the anchors be capable of resisting without fracture and/or pull-out a
force of 5000 lbs (22.2 kN). A similar test is performed on-site to verify strength of epoxy
adhesive roof anchors.
Pro-Bel wall anchors secured to structural concrete using epoxy adhesive are load tested
on-site using a hydraulic pull tester to verify strength and anchor bolt integrity.
Photo shows 8’-0” (2440 mm) high apparatus
used for shock (drop) testing of Pro-Bel safe-
ty U-Bar anchors. A 220 lb. (100 kg) weight
was connected to the anchor using a steel
test lanyard and dropped a distance of 4’- 0”
(1220 mm). A series of anchors employing
different securements were tested and peak
forces up to 18,522 lbs (8400 kg) were gener-
ated without fracture to any part of the
anchors.
A series of Pro-Bel safety U-Bar anchors
were tested to determine their ultimate
strength (destructive testing). The force
used to break the test specimens was pro-
vided by a hydraulic system, a hooking
mechanism, and support structure. The
highest pressure recorded just before a
specimen was broken in this series of tests
measured 32,445 lbs (4500 psi *7.210 in2).

PRO-BEL ROOFTOP SUPPORTS
Application
Recommended for use in new construction or retrofit applica-
tions where it is necessary or desirable to conceal the anchor
when not in use i.e. terrace, balcony or roof deck locations. Pro-
Bel flip-up and recessed anchors are designed to suit all roof
conditions including cast-in-place and weldment applications.
Application
Ideal for use in new contruction for exposed concrete bal-
conies where it is desirable to directly rig a bosun’s chair
over a balcony rail. If the rail cannot accommodate the loads,
outrigger beams may be employed for exterior maintenance
using a ground rigged platform. The embed anchor (con-
nector) is removed and capped flush when not in use.
Pro-Bel galvanized steel pipe support complete with U-Bar safety anchor.
Pro-Bel also manufactures a complementary line of rooftop supports for pipes, satel-
lite dishes, catwalks, cellular towers, antenna, guy wire securement, air conditioning
units and similar equipment. These supports can be supplied as stand alone items or
combined with U-bar safety anchors and are secured and flashed in using the same
reliable methods employed for Pro-Bel anchors. For further information contact a Pro-
Bel representative. 4

![](asset-a.png)
DESIGN CONSIDERATIONS
Roof Space: Conventional (non-perma-
nent) outrigger beams employing coun-
terweights, when used with descent con-
trolled bosun’s chair, single work cage or
platforms are normally supported to clear
a low non-structural parapet wall. Con-
ventional outrigger beams are typically
12’-0” to 15’-0” (3658 mm to 4572 mm)
long and have a reach of 3’-0” (915 mm)
or less beyond the roof edge. They
require sufficient space on the roof to
accommodate the inboard portion of the
beam and the tie-back.
Parapet Strength: If the parapet wall is
structurally sufficient, a parapet wall
clamp may be secured to the wall for the
suspension of access equipment.
Also, a bosun’s chair can be directly
secured to a safety anchor. This is known
as direct rigging. The chair is rigged
directly to wall or roof anchors in line with
the point of suspension, and the primary
synthetic rope suspension lines are nor-
mally protected at the parapet using con-
tractor supplied carpet or other anti-abra-
sion protection devices.
When the parapet is not capable of sup-
porting the applied loads, primary sus-
pension support equipment such as out-
rigger beam dollys or davits must be con-
sidered. See Pro-Bel Outrigger Beam
Systems or Davit Systems literature.
Parapet Height: Anchors can be
installed in parapet walls provided walls
meet the following criteria:
Wall is 42” (1067 mm) minimum
guardrail height;
Wall has been engineered to take the
applied loads.
Structural loads: Anchors are designed
to a maximum fall arresting force of typi-
cally 1800 lbs (8.0 kN) when wearing a
body harness with a safety factor of 2
without any permanent deformation and
to 5000 lbs (22.24 kN) against fracture or
detachment.
Free Design Service: The selection of
window cleaning equipment is a perfor-
mance oriented and highly specialized
field requiring an in-depth knowledge of
Rigging Methods, Safety and OSHA
Standards/State Codes. Pro-Bel provides
a free design service to ensure that Pro-
Bel systems are properly specified.
Pro-Bel portable outrigger with beam dolly is ideal for clearing non-structural parapet.
Note separate pier-type safety anchors for securing lifelines. See Pro-Bel Outrigger Beam
Systems literature.
This photo shows a Pro-Bel roof anchor
installation. Anchors are welded to struc-
tural steel before a horizontal lifeline cable
system is installed to provide fall protec-
tion on this arched roof.
Pro-Bel portable aluminum ground rigged
davit arms are ideal for clearing non-struc-
tural parapets or reaching out past build-
ing face obstructions. See Pro-Bel Davit

2.
Location of Lifeline Anchors: The
location of lifeline anchors relative to tie-
back anchors must be such that a work-
er can neither fall more than 6’-0” (1.8
m), nor contact any lower level (OSHA
1910.66, Subpart F and ANSI/IWCA
I-14.1, section 9.2.2 (g) 2). See Layout
data on page A-12.

ANCHOR LAYOUT PROCEDURE
1. Review the Pro-Bel System & Equipment
Introduction literature (pages G-6 to G-
18). This data provides an overview of the
various equipment options used to clean
windows or perform other suspended build-
ing maintenance.
2. Identify all roof levels. Mark window loca-
tions on other areas requiring access on
the architectural roof plan drawing(s).
3. Examine building section drawings to
assess construction of parapet wall,
mechanical room wall and roof assembly or
other building elements as necessary.
4. Examine roof structural drawings for possi-
ble anchorage locations.
5. Examine building elevations or other draw-
ings to identify any setbacks, recesses or
other unusual features.
6. Review the Design Considerations on page
A-10 to assist in making a "rigging" deci-
sion.
7. If it has been determined that "rigging" is
suited to using anchors only, for both the
support of primary suspension equipment
and lifelines, refer to Anchor Spacing Chart
at right on page A-12.
Note: Primary suspension equipment refers to
conventional, maintenance contractor supplied
equipment i.e. bosun's chair, transportable out-
rigger beams, single work cage, temporary
platform and parapet wall clamps.
ANCHOR PLACEMENT
1. After determining what areas of the build-
ing face will need to be accessed for main-
tenance, anchor locations can now be cho-
sen.
2. Anchors are located on the roof of the
building and are generally secured to any
or all of the following acceptable vertical or
horizontal elements: mechanical room curb
walls; parapet walls minimum 42" (1067
mm) high; roof mounted structural ele-
ments e.g. rooftop equipment structural
support beams or columns, and similar
structures; roof decks (to concrete slab,
precast deck, structural steel, and similar
structures); finished roof top terraces.
3. Ideally locations for Pro-Bel safety anchors
are in direct line with the anticipated
"drops" and are suited to both bosun's chair
and suspended platform. A "drop" for a
chair is typically a 6'-0" (1830 mm) wide
area, and 20'-0" to 28'-0" (7000 mm to
8535 mm) for a platform. Two anchors are
required for bosun's chair (1 primary and 1
lifeline) and 4 anchors are required for a
platform (2 primary and 2 lifeline).
4. Lifeline anchors and primary tie-back
anchors for transportable outrigger beams
and parapet wall clamps should be located
in line with the point of suspension (per-
pendicular) whenever practical, but should
not be offset more than 10'-0" (3084 mm)
measured horizontally from running at a
right angle to the building face at the point
of suspension. The angle created by the
offset distance should not exceed 25º. See
anchor spacing chart data on page A-12.
5. If a bosun's chair or similar single point
suspension equipment is used with the pri-
mary support lines directly attached to
anchors (direct rigging), the horizontal por-
tion of the descent line (that portion of the
support from the anchor to the roof edge)
should be in a plane at right angles to the
face of the building at the "drop". This
guideline will ensure that slide distance and
swing action in the event of a fall will be
reduced to a reasonably safe minimum
thereby lessening the potential for worker
collision injury, while allowing for self-
recovery.
Essentially, OSHA 1910.66, Subpart F and
ANSI/IWCA I-14.1, section 9.2.2 (g) 2
requires personal fall arrest systems be
rigged such that an employee can neither
free fall more than 6'-0" (1.8 m), nor contact
any lower level. Any anchor placement sce-
nario should reflect this requirement.

ANCHOR PLACEMENT (continued)
6. Locate the very first roof anchor, which
should be a primary suspension or tie-back
anchor. If the parapet wall is less than 42"
(1067 mm) guardrail height, this anchor
should be a minimum of 6'-0" (1830 mm)
distance from the parapet so that the work-
er can tie off whenever the worker has to
step within 6'-0" (1830 mm) of an unguard-
ed edge. If the parapet is minimum 42"
(1067 mm) high, the anchor can be located
any distance inside the parapet.
7. The second and subsequent primary sus-
pension or tie-back anchors can now be
located as per item 3.
8. After primary anchors have been located,
lifeline anchors can now be located relative
to the primary anchors using the anchor
spacing chart data at right.
9. Anchor spacing must be adjusted, of
course, to circumvent any obstruction.
Note: Pro-Bel tie-back/lifeline anchors and
direct rigging anchors are the same and are
used interchangeably.

When rigging primary lines, tie-back lines
and lifelines for a bosun’s chair, single
work cage or platform, there are many sce-
narios having an influence on whether
lines are anchored in line with or offset
from the point of suspension. Ultimately,
the object is to place the anchors in a man-
ner that will suit chair and platform loca-
tions within the variable work zones while
ensuring that the OSHA maximum free fall
distance of 6’-0” (1.8 m) is not exceeded, in
the event of a worker falling.
Recognizing this, Pro-Bel employ a 25O
angle placement criteria for the location of
both primary support lines and secondary
lifelines. This criteria will ensure that lines
are rigged within 15Oof the point of sus-
pension in accordance with the
ANSI/IWCA I-14.1 Window Cleaning
Safety Standard.

OTHER USES
Generally, Pro-Bel window cleaning/sus-
pended maintenance anchor systems are
economical or practical for all new or
retrofit buildings 3 storeys and higher
where windows or building facades are
accessed from the roof.
In addition to window cleaning applica-
tions, Pro-Bel safety anchor systems are
recommended for work such as:
• construction, restoration, cleaning,
sandblasting, caulking, or pointing;
• fall protection for ladder work using full
body harness and lanyard; and
• interior or exterior industrial applica-
tions wherever maintenance personnel
are exposed to falls from elevation.
Pro-Bel safety anchor systems are com-
patible with all types of suspended main-
tenance equipment and can be used
interchangeably for either tying off sus-
pended equipment or fall protection life-
lines.
BUILDING OWNER ASSURANCE
There is a shared responsibility between
the building owner/employer and the win-
dow cleaning/suspended maintenance
contractor. OSHA and ANSI/IWCA I-14.1
acknowledges that the building owner/
employer is the controlling employer and
must assure the contractor that the sys-
tem has been installed in accordance
with engineered drawings, test data
(when required), and equipment specifi-
cations. The building owner/employer
shall provide written assurance that the
installation has been annually inspected
and maintained to ensure that all equip-
ment is safe and operating as required.
Refer to Pro-Bel “Digest for Building
Owners, Property Managers, and General
Contractors” literature for more detailed
information.
AVAILABILITY & COST

maintenance safety systems are distrib-
uted throughout the United States,
Canada and internationally.
Budget pricing is provided on a project-
to-project basis for both materials and
installation, or materials only. See “Tech-
nical Consultation” at right.
FREE DESIGN SERVICE
The selection of window cleaning
equipment is a performance oriented
and highly specialized area. Also the
issues of fall protection and fall arrest
are serious concerns with OSHA
inspection authorities. Interpreting the
myriad of OSHA standards, including
the separate requirements of various
states, and proposed changes, is a
daunting task at best.
Each building is different, requiring an
individual technical approach and a
time commitment beyond the scope of
most professional offices. Even with a
high degree of knowledge and the
best of intentions, the planning
process can go askew. It is for these
reasons that Pro-Bel provides archi-
tects and engineers with a FREE
DESIGN SERVICE, and to ensure that
Pro-Bel Window Cleaning/Suspended
Maintenance Systems are properly
specified and installed.
