Steel City 54C3 Octagon/Round Outlet Box Cover, 2-3/4" Diameter

No. The 54C3 is a fixed steel round/octagon box cover with a raised profile and no moving parts. For an adjustable fixture mount on an octagon box, use the RACO 894KH KWIK-HANG Series 4 in. round swivel cover, which is built as a swivel cover for octagon boxes and lets the fixture be angled.

The Steel City 54C3 is a raised cover, offered in 1/2 inch, 5/8 inch, 1 inch, and 1-1/4 inch raised depths, so it adds box volume and stands off the box face. If you want a plain blank closure with no raised dome, the Mulberry 11700 F-35 Series galvanized steel oval/round blank cover is the one to specify instead - it is a blank cover, so it closes the box without providing a device opening.

It's steel, finished silver. Steel covers are what you want for mechanical durability and for maintaining the metallic enclosure on a metal box system, but bare steel in a wet location is not the right call. For damp or wet exterior work, use a weatherproof cover rated for the location instead.

The 54C3 is a raised closure cover, not a fixture support. If you're hanging a fixture and need adjustment at the box, the RACO 894KH KWIK-HANG Series 4 inch round swivel cover for octagon boxes is the swivel-type alternative on the same 4 inch octagon opening.

Stock by the condition, not one size. The 1/2 and 5/8 inch raises handle most flush-mount device work; the 1 inch and 1-1/4 inch raises are for boxes set back behind thick finish material or where a bulkier device needs clearance. Part numbers run 54 C 3 1/2, 54 C 3, 54 C 3 1 and 54 C 3 1 1/4, all steel, all for 4 inch round or octagon boxes, so they look identical once installed.
