RACO RACO857 – Frequently Asked Questions

1) Will the RACO 857 cover fit a 4-11/16 in. square box?
Yes. The RACO 857 is a 4-11/16 in. square cover sized to the standard 4-11/16 in. square box footprint, so it lands flush on the box with no adapter ring. It will not work on a 4 in. square box, which is a smaller opening and needs a 4 in. square cover instead.
2) Can I use the RACO 857 for two GFCI receptacles, or is it decorator only?
Either. The 857 is configured to take two GFCI devices or two Decorator (rectangular-face) devices in the same cover, so one part number covers both. What it will not take is standard duplex receptacles with the round-ear yokes, which need a duplex-configured cover.
3) Is this an exposed-work cover or a flush/flat box cover?
It is an exposed-work (surface) cover, built for boxes mounted on the face of a wall or ceiling with visible conduit. If the box is recessed in finished drywall, you want a flat device cover or a plaster ring with a wallplate, not this one.
4) I need to standardize GFCI covers across a building. Does one 857 handle both device styles?
It does, and that is the reason to stock it. Because the same 4-11/16 in. square cover accepts two GFCIs or two Decorator devices, a property or MRO stockroom can carry one part number instead of two and still match whatever device goes in the box on a given opening.
5) What is the exact RACO part number for the 4-11/16 in. square two-GFCI exposed cover?
RACO 857. That is the manufacturer part number as well, so it is what you put on a purchase order or a submittal for the 4-11/16 in. square two-device exposed-work cover.
6) Where can I get the spec sheet for the RACO 857 cover for a submittal package?
RACO publishes a spec sheet for the 857 at https://hubbellcdn.com/specsheet/RACO-857-SPEC-EN.pdf. That is the document to drop into a submittal when the drawing calls out a 4-11/16 in. square exposed-work device cover.
