RACO RACO838 – Frequently Asked Questions
1) Will the RACO 838 cover fit a 4 in. square box, or only a 4-11/16 in. box?
Only 4-11/16 in. square boxes. The 838 is sized at 4-11/16 in. square and matches that footprint; a 4 in. square box (commonly called a 1900 box) needs a 4 in. square cover instead. The two sizes are not interchangeable, and the mounting screw holes will not line up.
2) Why would I use a 3/4 in. raised cover instead of a flat box cover?
The 3/4 in. raised profile on the RACO 838 adds interior clearance, so a switch or receptacle plus its conductors has room without crowding the box. A flat blank cover closes out a box with no device in it. If you are mounting a single-gang device on a 4-11/16 in. square box and the wiring is tight behind it, the raised cover is what buys you the depth.
3) Is the RACO 838 a single-gang or two-gang cover?
Single gang. The 838 has a 1-gang device opening on a 4-11/16 in. square body, so it takes one switch or one receptacle. For two devices on the same 4-11/16 in. box you need a 2-gang raised cover, not this one.
4) Can I use the RACO 838 to close out a 4-11/16 in. junction box with no device in it?
It is built as a device cover, so the face carries a single-gang opening. Used over a junction box, that opening has to be filled by a device or a matching single-gang blank plate. If the box is purely a splice point with nothing to mount, a flat blank 4-11/16 in. square cover is the cleaner close-out.
5) Which RACO part number do I order for a 4-11/16 in. 1-gang 3/4 in. raised cover?
Order RACO 838. That is the manufacturer part number for the 4-11/16 in. square, 1-gang raised cover at 3/4 in. depth. Raised covers are depth-specific, so if your drawing calls for a different raised height the part number changes.
6) What does drawn construction mean on a box cover, and does it matter?
Drawn means the 838 is formed from one piece of steel with no weld seam. On a raised cover that matters for fit: the raised section and the flange are continuous, so the cover seats consistently against the box face with fewer gaps to shim or caulk. A welded cover is built from joined pieces.
7) Is there a spec sheet for the RACO 838 cover I can submit with my package?
Yes, RACO publishes a spec sheet for the 838 at https://hubbellcdn.com/specsheet/RACO-838-SPEC-EN.pdf. That is the document to drop into a submittal when the spec calls for a 4-11/16 in. square raised device cover.
