RACO RACO773 – Frequently Asked Questions
1) Will the RACO 773 cover fit a standard 4 in. square electrical box?
Yes. The RACO 773 is sized for standard 4 in. square boxes and sits over the box opening as a one-device cover. It is a square cover, so it matches the square box opening rather than an octagon or round box.
2) How much extra depth does the 773 raised cover add behind the device?
The 773 has a 3/4 in. raised profile, so it adds that much interior clearance above the box for device wiring, terminations, and the device yoke. That extra room is the reason to pick a raised cover over a flat one when a switch or receptacle is crowding the box.
3) Can I mount two devices on the RACO 773, or just one?
One. The 773 is a 1-device cover with a single opening, suited to a single switch, receptacle, or dimmer. For two devices in the same 4 in. square box you need a 2-device (two-gang) raised cover instead.
4) Do I need a separate wall plate with a RACO 773 raised cover?
The 773 is the raised device cover itself, with the single device opening. It carries the device and finishes the box, but the faceplate or wall plate for the switch or receptacle is a separate item, as are the device mounting screws supplied with the device. Order the plate to suit the device style you're installing.
5) Is the RACO 773 box cover drawn or welded, and does it matter?
Drawn, one-piece construction. There are no welded seams, which gives consistent dimensional accuracy where the cover lands on the box edge. Welded covers are the alternative construction you'll see on some square covers; for the 773 the spec is drawn.
6) Where is a 4 in. square raised device cover like the RACO 773 typically used?
Commercial and industrial branch-circuit and junction work, where a 4 in. square box houses a single switch, receptacle, or dimmer. It is used on new construction and on renovation where an existing 4 in. square box is being converted to a device location.
7) What is the manufacturer part number for the RACO 4 in. square one-gang raised cover?
The part number is RACO 773, a 4 in. square 1-device raised cover with a 3/4 in. raise and drawn construction.
