FM7™ Grayloy™-Iron and Aluminum Unilet®
Conduit Bodies: Wedge-Lok™ Clip Covers
For use with Rigid Steel, Rigid Aluminum and IMC Conduit.
Interchangeable. Appleton FM7 bodies, covers and
gaskets are completely interchangeable with equivalent
Crouse-Hinds Form 7* bodies and covers.
Applications and installation dimensions are also inter-
changeable.
No wire damage. Appleton FM7 bodies have a smooth,
rounded, internal bushing in each hub and smooth cover
openings to protect conductor insulation.
Easy cover removal. Unique FM7 Wedge-Lok Clip-Cover
design allows easy removal at any later time, without dam-
aging the conduit body. Because the cover is secured with
clips– not screws – no retapping of corroded body screw
holes is necessary to replace cover.
Positive-seating cover screws. Pan-head stainless steel
cover screws, which hold the clips, provide superior screw-
driver seating and torque for easier cover installation or
removal. Each cover screw and its attached locking clip
are held captive in the cover to prevent loss.
Full-line choice. Appleton FM7 bodies are offered in a
complete range of hub configurations and sizes. FM7
covers are available in blank stamped steel or stamped
aluminum, and also in cast Grayloy-iron or cast alumi-
num. Covers can be used without gaskets, or with a solid
neoprene gasket. All Appleton FM7 bodies, covers and
gaskets are interchangeable with Crouse-Hinds Form 7*
bodies, covers and gaskets.
Approved for wet locations.
FM7 Grayloy-iron bodies with cast covers and gasket are
approved for use in wet locations. (NEMA 3R)
Maximum corrosion protection. Appleton FM7 Grayloy-
iron conduit bodies and cast covers have a triple-coat fin-
ish– (1) zinc electroplate, (2) dichromate, and (3) epoxy
powder coating. FM7 aluminum bodies and cast covers are
coated with epoxy powder coating. FM7 blank steel covers
have a zinc electroplate finish. Superior FM7 finish gives
greater corrosion protection in wet or harsh environments,
assuring long, trouble-free service.
Grayloy-iron properties. Grayloy™ is an Appleton pro-
prietary cast graphite flake gray iron alloy with superior
physical and mechanical properties offering strength, hard-
ness, fracture toughness, high vibration absorption and
dimensional stability. Tensile strength is similar to ASTM-

Mogul Unilet® Conduit Outlet Bodies:
NEC 6x8x Series (C, LB and UB)
and Types LL, LR and T
For use with Threaded Rigid Metal Conduit and IMC.
Complete with Assembled Cover and Neoprene Gasket.
Applications
• Larger body size facilitates pulling of
large and heavy conductors. Specially
designed raised cast covers provide
additional wiring area.
• Mogul Unilets® for pulling straight,
45° or 90° angle turns and/or making
taps and splices.
Features
• LB and UB Moguls
Length Requirement: distance between
centerline of each hub bushing (con-
duit stop) exceeds six times the trade
diameter of the conduit per NEC 314-
28(a)(2).
Bending Space Requirement: these
moguls also meet the NEC 314-28(a)(2)
Exception requirement spelled out in
NEC 312-6(a) Table.
• C Moguls
Length Requirement: distance between
centerline of each hub bushing (conduit
stop) exceeds eight times the trade
diameter of the conduit per NEC 314-
28(a)(1).
Bending Space Requirement: not ap-
plicable.
•
LL and LR Moguls: Like LB moguls,
these moguls have an end hub. However,
the second hub is in the side (LL left
and LR right) instead of the back.*
• T Moguls: These are like “C” moguls
(1” thru 4”), except with an additional
middle side hub. Distance between the
centerline of each “C” hub conduit stop
exceeds eight times the trade diameter
of the conduit per NEC 314-28(a)(1).*
• Exclusive built-in rollers facilitate
cable pulling. Available on NEC 6x8x
Series Moguls (C, LB and UB) in sizes
1-1/4” and up.
•
Smooth, rounded integral bushing in
each hub protects conductor insulation.
• Accurately tapped, tapered threads for
tight, rigid joints and ground continuity.
• Covers have captive stainless steel
screws to speed installation, prevent
“freezing” of screws.
*If less than maximum conductors permit-
ted by NEC are used, smaller wires may be
used additionally through “LL”, “LR” or “T”
hubs. If large conductors are required to be
bent in “LL”, “LR” or “T” direction, order junc-
tion boxes instead from Cat. Sec. C.
Standard Materials
• Malleable iron or aluminum.
