RACO 833 4-11/16 in. Flat Square Cover with Centered 1/2 in. KO

The RACO 833 is a 4-11/16 in. square flat cover designed to close and protect square electrical boxes used throughout commercial, industrial, and residential wiring systems. This flat, square-shaped cover features a centered 1/2 in. knockout that allows electricians to route conduit or fittings through the center of the plate without additional layout or drilling. Manufactured to meet demanding jobsite standards, the RACO 833 is cULus Listed, giving contractors and inspectors confidence that the product meets recognized safety requirements for electrical installations. Its flat profile keeps the finished box assembly low and unobtrusive, making it a practical choice wherever a simple, reliable square box cover is required.

Key Features

  • Trade Size: 4-11/16 in. square cover sized to match standard 4-11/16 in. square electrical boxes for a secure, accurate fit.
  • Flat Square Profile: The flat square design sits cleanly over the box opening, providing a finished, low-profile appearance suitable for concealed and exposed installations.
  • Centered 1/2 in. Knockout: A single, centered 1/2 in. knockout is pre-positioned in the middle of the cover, simplifying conduit or fitting entry and eliminating off-center measuring.
  • cULus Listed: Independently certified to cULus safety standards, supporting code-compliant installations inspected under recognized electrical codes.
  • Purpose-Built Cover: Engineered specifically as a cover for straightforward stocking and use wherever a plain square box closure is needed.
  • Compatible Square Box Fit: Matches the 4-11/16 in. square box family widely used in commercial and industrial branch-circuit wiring.
  • Simple Installation: The centered knockout and flat design allow quick installation with standard mounting screws, reducing labor time on the jobsite.

RACO RACO833 – Frequently Asked Questions

1) Will the RACO 833 cover fit a 4-11/16 in. square box?
Yes. The RACO 833 is sized to the 4-11/16 in. square box family, so it closes standard 4-11/16 in. square outlet, junction, and pull boxes. It will not fit a 4 in. square box, which is the other common size in commercial branch-circuit work; for those you need a 4 in. square cover instead.
2) Does the RACO 833 square cover come with a knockout for conduit?
It has one 1/2 in. knockout, centered in the plate. That lets you bring a 1/2 in. fitting or conduit straight out of the middle of the box with no layout or drilling. If you need a blank closure with no opening, or multiple entries, this is not the cover for it.
3) Flat cover or raised (mud-ring) cover for a 4-11/16 in. box?
Use the 833 flat cover when you only need to close the box, as on a junction or pull box, or when a conduit run exits through the center. The flat profile sits right on the box opening and keeps the assembly low. If you are landing a device (receptacle or switch) or bringing the opening out to a finished wall surface, you want a raised device cover or mud ring, not a flat cover with a single centered knockout.
4) What do I need to install the RACO 833 cover, and are screws included?
The 833 mounts with standard box cover screws into the box ears. Plan on the 1/2 in. fitting or connector for the centered knockout if you are running conduit through it; that fitting is a separate item.
5) What is the RACO part number for the 4-11/16 in. flat square cover with a center 1/2 in. knockout?
RACO 833. That is the manufacturer part number to order by, and it is the 4-11/16 in. square flat cover with the single centered 1/2 in. knockout.
