RACO RACO856 – Frequently Asked Questions
1) Will the RACO 856 cover fit a 4-11/16 in. square box?
Yes. The RACO 856 is a 4-11/16 in. square cover sized to match the opening on standard 4-11/16 in. square outlet and device boxes, so it sits flush on the box ears. It will not work on a 4 in. square box (commonly called a 1900 box) or on a 4 in. octagon, both of which need a cover sized to those footprints.
2) Can I use the RACO 856 for a decorator rocker switch, or is it GFCI only?
Both. The 856 carries a GFCI configuration opening, and because GFCI receptacles and decorator (rocker) devices share the same rectangular face dimensions, the same opening takes a decorator switch or a decorator-style receptacle. What it will not take is a standard duplex receptacle with the two figure-eight openings, or a toggle switch.
3) Is this RACO cover suitable for surface-mounted exposed conduit work, or is it a flush wall plate?
It is an exposed work cover, not a flush wall plate. The 856 mounts directly on a surface-mounted 4-11/16 in. square box and stays visible after installation, which is what you want on exposed conduit runs in garages, mechanical rooms, warehouses and shops. If the box is recessed in finished drywall, you want a flat flush plate instead.
4) Is the RACO 856 cover UL listed for commercial jobs?
The 856 is cULus Listed, which covers both US and Canadian requirements and is what an inspector looks for on commercial and residential device box work.
5) Do I need anything else besides the cover to finish a GFCI in an exposed 4-11/16 square box?
The cover completes the box assembly over the device and protects the wiring connections, but the GFCI receptacle or decorator device itself is a separate item, as is the box. Mounting screws for the device to the cover and the cover to the box are standard 6-32 hardware on this style of exposed work cover.
6) I'm standardizing GFCI covers across a building with 4-11/16 square boxes. Does the RACO 856 come in more than one version?
The 856 is a single part, one model number, so every unit you order is the same 4-11/16 in. square GFCI/decorator cover. There is no finish or size choice to track, which makes it straightforward to spec repeat quantities for a whole facility and keep the look consistent across openings.
7) What is the exact RACO part number to order this GFCI square cover, and where can I get the spec sheet?
Order it as RACO 856. The manufacturer publishes a spec sheet for it at https://hubbellcdn.com/specsheet/RACO-856-SPEC-EN.pdf, which is the document to attach when a submittal package calls for cut sheets.
