FM7™ Grayloy™-Iron and Aluminum Unilet®

Conduit Bodies: Wedge-Lok™ Clip Covers;

FM8® Grayloy™-Iron Conduit Bodies and Covers

For use with Rigid Steel, Rigid Aluminum and IMC Conduit.

Freedom of Choice. With new FM8 series added to

Appleton’s full-line family of conduit bodies, you have a

single source for the right choice needed for every job– FM8

Grayloy-iron bodies and covers, FM7 Grayloy-iron or alumi-

num threaded bodies and covers... malleable iron Form 35...

aluminum Form 85... and malleable iron or aluminum NEC

Mogul 6x8x.

Interchangeable. Appleton FM7 and FM8 bodies, covers

and gaskets are completely interchangeable with equiva-

lent Crouse-Hinds Form 7* and Form 8* bodies and covers.

Applications and installation dimensions are also inter-

changeable.

No wire damage. Appleton FM7 and FM8 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 and FM8 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 aluminum.

FM8 covers are available in Grayloy-iron. Covers can be

used without gaskets, or with a solid neoprene gasket. All

Appleton FM7 and FM8 bodies, covers and gaskets are

interchangeable with Crouse-Hinds Form 7* and Form 8*

bodies, covers and gaskets.

Approved for wet locations. FM7 and FM8 Grayloy-iron

bodies with the “FG” series cast covers and gasket are

approved for use in wet locations. (NEMA 3R)

Maximum corrosion protection. Appleton FM7 and FM8

Grayloy-iron conduit bodies and cast covers have a triple-

coat finish– (1) zinc electroplate, (2) dichromate, and (3)

epoxy powder coating. FM7 aluminum bodies and cast cov-

ers are coated with epoxy powder coating. FM7 and FM8

blank steel covers have a zinc electroplate finish. Superior

FM7 and FM8 finish gives greater corrosion protection in wet

or harsh environments, assuring long, trouble-free service.

Grayloy-iron properties. Grayloy™ is an Appleton propri-

etary cast graphite flake gray iron alloy with superior physical

and mechanical properties offering strength, hardness, frac-

ture toughness, high vibration absorption and dimensional

stability. Tensile strength is similar to ASTM-A48 Class 30A

(30,000 tensile), with Brinell hardness of approximately

180BH.

Aluminum properties. Aluminum products are produced

from a high strength copper-free (4/10 of 1% max.) alloy.

More wiring space. Appleton’s FM7 and FM8 flat-back

design provides greater cubic content for easier wire pulling,

and more room for splicing. FM7 and FM8 flat back fits flush

and snug against flat surfaces for more stable installation.

* Form 7 and Form 8 are products of Crouse-Hinds, a member company of

Cooper Industries.

Appleton FM7:

• Maximum wire number/size and cubic capacity molded into body.

• Large size, style and compliance data molded into body.
