RACO 812C – Frequently Asked Questions

1) Will the RACO 812C cover fit a standard 4 in. square exposed work box?
Yes. The 812C is a 4 in. square cover made to match the footprint of standard 4 in. square exposed work outlet boxes, so it seats flush over the box with the square profile lining up on all four sides. It is intended for surface-mounted boxes that stay visible after the job is done, not for boxes recessed behind drywall with a flat plaster ring.
2) What kind of receptacle goes in the RACO 812C cover, and will a standard duplex outlet work?
The opening is a single 1.62 in. diameter round hole, sized for one round 20A receptacle device. A standard duplex receptacle will not fit, since that needs a figure-eight duplex opening. If you are installing a duplex device on a 4 in. square exposed work box, you need a duplex-configured cover instead of this round one.
3) Can I use the RACO 812C on a surface-mounted box in a garage, warehouse, or basement?
That is exactly what an exposed work cover is for. The 812C is configured for surface or exposed installations where the box and cover both stay visible, which is the normal condition in garages, shops, warehouse walls, and unfinished basements running surface conduit. It gives the box a finished face without needing any wall covering around it.
4) What is the correct RACO part number to order for a 4 in. square round 20A receptacle cover?
Order RACO 812C. There is one configuration, model 812C, a 4 in. square exposed work cover with a single round receptacle opening, so there are no finish or size options to specify.
5) Where can I get the spec sheet for the RACO 812C cover for a submittal package?
RACO publishes a spec sheet for the 812C through Hubbell at https://hubbellcdn.com/specsheet/RACO-812C-SPEC-EN.pdf. That is the document to drop into a submittal or RFI when an engineer wants the 4 in. square exposed work cover confirmed against the drawing.
