RACO 775 – Frequently Asked Questions
1) Will the RACO 775 cover fit a standard 4 inch square electrical box?
Yes. The RACO 775 is sized for standard 4 inch square boxes, so it lands on the box ears and closes the opening flush. Product size is listed at 4 in with a square profile, which matches the common 4 inch square (1900 box) footprint used in commercial rough-in.
2) How much extra depth does a 1-1/4 inch raised square cover add inside the box?
The RACO 775 raises the device plane 1-1/4 inches above the box face, so it adds that much usable volume behind the switch or receptacle. That is the reason to pick it over a flat cover: it buys back wire bending space when the box is crowded with conductors, splices, and a device body.
3) Should I use a flat box cover or a 1-1/4 inch raised cover on a 4 inch square box?
Use a flat cover when the box is a pure junction with no device, or when the device fits with room to spare. Go to the 775 raised cover when you are mounting a device in a 4 inch square box that is tight on fill, when the box is set back behind finished wall material, or when you need the device face to sit proud of the surface. The 1-1/4 in raise gives you the clearance a flat plate does not.
4) How many devices does the RACO 775 cover hold?
One. The 775 has a single device opening, so it carries one switch, one receptacle, or one similar device per cover. For two devices in the same 4 inch square box you need a 2-device (two-gang) raised cover instead.
5) Can I use the RACO 775 raised cover in a renovation where the 4 inch square box is set deep in the wall?
That is one of its normal uses. The 1-1/4 in raise brings the device forward from the box face, which helps when an existing 4 inch square box sits behind added drywall or furring in a remodel. It also keeps the single device opening aligned to a standard square box footprint, so you are not re-prepping the box.
6) What does drawn construction mean on a raised device cover, and does it matter?
Drawn means the cover is formed from a single piece of steel rather than built from welded seams, so wall thickness stays consistent and there are no weld joints to crack or burr. For an electrician it means a smoother edge around the device opening and a uniform finished appearance where the cover shows. The RACO 775 is drawn.
