2.2 Installation of door panels
2.2.1 Calculation of panels width
Dividing
(opening width + l + c/2+ d/2) by
the total number of panels, normal
panels width (x) is calculated.
To calculate the fixed panel width (z)
subtract (l + c/2 + d/2) from x.
Example:
3 - leaf end folding door
Clear opening width = 2200mm
Panel thickness (c) = 40mm
Hinge diameter (d) = 8mm
Dimension (l) =20mm
Calculation:
2200 + 20 + 20 + 4 = 2243mm
Normal Panel width (x) : 2243 ÷ 3 = 748mm
Fixed panel width (z) : 748-44 = 704mm

STEP 1: The edges of each track enter
the joint and meet in the centre.
STEP 2: The four bolts at the top of the
joint have to be bolted so that the track
has tight contact with the joint, creating
a flat running surface through the joint.
STEP 3: The four side bolts are used to
achieve horizontal alignment within the
joint.
B49: Installer should follow the next steps:
3MULTIPLE PANEL FOLDING DOOR
.B49
When using more than one piece of
track profiles (due to many panels
or group of panels) a splice joint
(.B49) is required in order to join
the tracks.

22
INSTALLATION, OPERATION & MAINTENANCE MANUAL
for folding door systems
Version June 2017

Care must be taken with the following:
Alignment of the two parts both to horizontal and vertical level is absolutely necessary in order to
avoid any problem to trolleys rolling inside the tracks. The gap between the two parts of track must
be as small as possible.
Track Profiles should be
vertical and horizontal aligned
Pay particular attention when supports are used around a splice joint. The joint is used only for
connection and does not support any load. The joint must be supported either side by additional
support brackets. These supports must not be omitted.
Important information for multiple panel folding door system
When you are using splice joint it is necessary to place support brackets at the right and
left side of the splice joints with the minimum distance between the joint and the bracket.
An odd number of panels indicates that the last panel will operate as an opening door.
At the bottom of previous panel a stabilization latch must be installed.
An application with 2 group of panels, requires that at least the one of them has to have
odd number of panels so when groups meet in the middle, the wheel hangers won’t hit
each other.
For wide door openings, NIKO recommends two groups of panels (one group folds at the
right side and the other at the left). For optimal operation, when having one group of pan-
els, do not use more than 7 panels.

Dividing (opening width + c/2* + d/2**) by the total number of half panels, the width of the half
normal panel is calculated. Multiply by 2 (x2) to calculate normal panel width.
To calculate the fixed panel width, subtract (c/2+d/2) from the half normal panel width.
Example: 4 and 1/2 folding door panels
Clear opening width = 3000mm
Panel thickness (c) = 40mm
Hinge diameter (d) = 8mm
Calculation:
3000 + 20 + 4 = 3024mm
Half Normal Panel width (x/2) : 3024 ÷ 9 = 336mm
Normal panel width (x) : 336 x 2 = 672mm
Fixed panel width (z) : 336 - 24 = 312mm

Make sure to test the screws for slack at regular inervals.
(1 month after first usage, half year and then one time every year is recommended).
The first inspection should be done one month after the folding door’s installation.
At that time, the following should be checked:
Horizontal and vertical alignment of the track profile must be checked.
All the elements of the folding door have to be inspected for any unusual wear-out.
All the bolts and nuts should be properly tightened.
All splice joints have to be aligned correctly.
All the wheel hangers have to roll smoothly.
Even though “NIKO®” folding door systems do not require any special maintenance, periodic checks
should be done. These checks combined with proper installation increase the system’s lifetime.
