RACO RACO722 – Frequently Asked Questions
1) Will the RACO 722 cover fit a standard 4 inch octagon box?
Yes. The RACO 722 is sized for standard 4 in. octagon electrical boxes, the common ceiling and wall junction box. It is a blank flat cover, so it closes the box rather than mounting a device or supporting a fixture.
2) Can I mount a light fixture or receptacle to the RACO 722 octagon cover?
No. The 722 is a solid blank with no device cutouts and no knockouts, so there is nothing to mount to. It is for closing out an octagon box that has no fixture or device at that point. If you need a fixture or device at that location, order an octagon cover with the matching device opening or fixture stud instead.
3) Is a blank cover on an abandoned junction box acceptable to an inspector?
Code requires every junction box to remain accessible and closed with an approved cover, and the RACO 722 is a cULus Listed cover made for exactly that: closing an octagon box where splices remain but no device or fixture is installed. Keep the box accessible, do not bury it behind drywall, and the blank cover is the correct closure.
4) What is the difference between the RACO 722 octagon cover and the Mulberry 11700 blank cover?
The RACO 722 is a 4 in. flat blank cover shaped to close standard 4 in. octagon electrical boxes, with no device cutouts or knockouts, and it is cULus Listed. The Mulberry 11700 is an F-35 Series galvanized steel oval/round blank cover in 3/4-inch size, so it is built for a small oval/round opening rather than a 4 in. octagon box. If the box in the ceiling or wall is a 4 in. octagon, the 722 is the cover that matches the shape and trade size; the Mulberry 11700 suits the smaller round/oval application.
5) Does the RACO 722 sit flush, or will it stand off the ceiling?
It is a flat profile cover that sits against the face of the box, so it keeps a low, clean line on a finished wall or ceiling. A raised or domed cover is what you would use if you needed extra interior volume for splices.
6) Is the Mulberry 11700 a direct substitute for the RACO 722 on a ceiling junction box?
No. Both are blank covers with no device openings, but they close different box shapes and sizes. The RACO 722 is a flat blank cover for 4 in. octagon boxes, the type commonly found at ceiling and wall junction points, and it carries a cULus Listing. The Mulberry 11700 is an oval/round blank cover in 3/4-inch size. For a 4 in. octagon ceiling junction box, the 722 is the matching cover.
7) What part number do I order for the RACO flat blank octagon cover?
Order RACO model 722. It ships as a single model with no finish or size options to specify.
8) Can I use the RACO 722 to temporarily close a box during a remodel?
That is one of its normal uses. The 722 works for new construction, remodel and retrofit, and routine maintenance, closing an octagon box either temporarily while work is pending or permanently where no device will ever be installed.
