Steel City 4S Square Outlet Box Cover

Five options on the 52 C 49 family: 1/2 inch (52 C 49 1/2), a 1/2 inch -30 version (52 C 49 1/2-30), 3/4 inch (52 C 49 3/4), 1 inch (52 C 49 1), and 1-1/4 inch (52 C 49 1 1/4). Pick the raise by how much extra wiring volume you need and how far the device has to come forward to sit flush with the finished wall surface.

For a conduit-hung box, use the RACO 897KH instead. It is a KWIK-HANG Series swivel cover for a 4 inch square box rated for 1/2 or 3/4 inch pipe, so the pipe connection and swivel are part of the cover. The Steel City 52 C 49 is a raised square cover in 1/2 inch through 1-1/4 inch depths and has no pipe takeoff, so it will close and extend the box but will not support it from conduit.

Both fit a 4 inch square outlet box, but they do different jobs. The Steel City 52 C 49 is a steel raised square box cover offered in 1/2 inch, 3/4 inch, 1 inch and 1-1/4 inch raised depths, so it adds box volume and brings the device or wiring space forward from the box face. The RACO 897KH is a KWIK-HANG Series swivel cover for a 4 inch square box, built to take 1/2 or 3/4 inch pipe, so it is the piece you use when the box has to hang from or pivot on conduit. If the drawing calls for extra cubic inches at the box face, the 52 C 49 raised cover is the match; if it calls for a pipe-supported box, the 897KH is.

A raised (extension) cover does two things a flat cover cannot: it adds cubic inches of box volume for conductor fill, and it brings the device or closure forward so it finishes flush with drywall, tile, or block. The 52 C 49 covers are offered from 1/2 inch up to 1-1/4 inch of raise for exactly that reason. If the box is already flush with the finished surface and fill is not tight, a flat blank cover is the simpler choice.

No, those numbers describe different dimensions. On the RACO 897KH, 1/2 and 3/4 inch refer to the pipe size the swivel cover accepts. On the Steel City 52 C 49 1/2 and 52 C 49 3/4, the 1/2 and 3/4 inch are raised depths - how far the steel cover stands off the face of the 4 inch square box - and the same family continues at 1 inch and 1-1/4 inch. Order the 52 C 49 by the depth you need at the box face, not by a conduit trade size.

Steel, in a silver (galvanized-look) finish. That matters if you are matching existing metal boxes and raceway in a commercial or industrial install, and it means the cover will bond to the box's grounding system rather than needing a separate nonmetallic approach.
