Steel City 52C1-50R 4 SQ BX CVR FLAT 50PK

Yes. The Steel City 52C1-50R is a flat square cover sized for 4 inch square outlet boxes, so it mounts to the standard two-screw pattern on a 4 in. square box. It is a blank flat cover with zero knockouts, so it closes the box off completely rather than supporting a device or fixture.

It is blank. The 52C1 flat cover has no knockouts and no device opening, which makes it the right part for closing out a junction box or a splice box. If you need to mount a switch, receptacle, or fixture, you need a device ring or a raised cover instead, not this one.

The 52C1-50R is Steel City's 50-piece pack designation for the 4 in. square flat cover, and the selling unit of measure on it is each, so a quantity of one is one pack carton. Order by the piece count you need on the job and treat each unit as the carton.

They close the same size box but do different jobs. The Steel City 52C1 is a flat square cover for a 4 inch box, pre-galvanized steel with no knockouts, so it blanks the box off at the surface. The RACO 897KH is a KWIK-HANG Series swivel cover for a 4 in. square box sized for 1/2 or 3/4 in. pipe, so it supports a fixture or conduit drop off the box rather than simply covering it. If the box is being closed out with nothing hanging from it, the flat 52C1 is the one; if a pipe stem or pendant has to land on the box, the swivel cover is the one.

That is exactly the use. A flat blank steel cover closes a 4 in. square junction box so the splices stay enclosed but can be reopened by removing two screws. It is pre-galvanized steel, which suits dry indoor locations; it is not a gasketed weatherproof cover, so for wet or damp exterior locations use a weatherproof cover with a gasket.

The flat Steel City 52C1 is the one to standardize on for blank-offs. It is a plain square steel cover for 4 inch boxes in a pre-galvanized finish, UL E2969, with no knockouts to seal. The RACO 897KH is a swivel cover intended for a 1/2 or 3/4 in. pipe connection, which is more hardware than a dead box needs. Stock the flat cover for closeouts and bring in the swivel cover only where fixtures hang.

Pre-galvanized steel with a silver appearance. The zinc coating handles the humidity of an unconditioned mechanical room or attic better than bare steel, but pre-galvanized is an indoor, dry-location finish. For exterior or wash-down areas, step up to a weatherproof cover rather than relying on this one.

Yes, country of origin on the 52C1-50R is the United States. That matters on government and institutional work with domestic-content requirements on the bid.
