RACO Square Flat Blank Cover

The RACO Square Flat Blank Cover is a 4 in. square flat blank cover engineered to provide a clean, finished closure for 4 in. square electrical boxes. With a solid, flat blank design that features no device or fixture cutouts, this cover is the go-to solution when a junction box is used strictly for splicing conductors and does not require a switch, receptacle, or fixture mounted to it. The square configuration is sized to align precisely with standard 4 in. square box openings, helping installers achieve a secure, flush, professional-looking finish. Whether used to cap off a spare box location during rough-in or to properly terminate a box that no longer requires a device, this cover delivers a neat, professional appearance while keeping wiring protected and enclosed. Backed by cULus Listing, the cover gives electrical contractors and maintenance professionals a code-recognized option for both new construction and renovation wiring projects.

RACO 752 – Frequently Asked Questions

1) Can I use a RACO blank cover on a junction box that only has splices in it?
That is exactly what it is for. The cover is solid with no device or fixture cutouts, so it closes a box used strictly for splicing conductors. If you later need to mount a switch, receptacle or luminaire on that box, you swap it for a device or fixture-style cover instead.
2) What is the difference between a flat blank cover and a raised or mud ring cover for a 4 inch square box?
A flat blank sits flush on the box face and has no openings at all, so it only closes the box. A raised cover or plaster ring adds depth and a device opening so a switch or receptacle can be mounted and brought out to the finished wall surface. If there is no device going in the box, the flat blank is the right choice; if there is, you need the ring.
3) Can I leave a spare 4 inch square box capped with a blank cover during rough-in and add a device later?
Yes. Capping a spare or future-use box location is one of the standard uses for this cover. It keeps the wiring enclosed and protected behind the wall or ceiling until the box is needed, and it comes off with the two cover screws when you are ready to install a device.
4) Is a RACO 752 cover interchangeable with other brands of 4 inch square boxes?
The 752 is sized to the standard 4 inch square box opening, which is a common industry footprint with cover screw holes on the same centers regardless of who made the box. It is not brand-specific to RACO boxes, though RACO lists it as pairing with their 4 inch square boxes as a complete box-and-cover assembly.
5) Do I need a blank cover on an accessible junction box, or can I leave it open?
A junction box has to be closed. Leaving splices exposed in an open box is not an acceptable finish, and a blank cover is the simplest way to close one that carries no device. This RACO cover is cULus Listed for that purpose on both new construction and renovation wiring.
