Center Knockout is engineered to close out standard 4 in. octagon junction boxes across residential, commercial, and light industrial electrical installations.

RACO RACO724 – Frequently Asked Questions

1) Will the RACO 724 cover fit a standard 4 inch octagon junction box?
Yes. The RACO 724 is a flat cover sized for standard 4 in. octagon junction boxes, closing the box opening flush. It is not made for 4 in. square boxes or round pan boxes, so if the box in your ceiling is square, you need a square cover instead.
2) What is the 1/2 inch center knockout on the RACO 724 octagon cover used for?
The knockout sits at the center of the cover and is pre-formed at 1/2 in., so you can punch it out for a conduit connection or to pass a fixture stud through when hanging a light. Leave it in place and the cover closes the box out solid. That center location is why this cover is commonly used at fixture drops rather than a blank cover.
3) Is the RACO 724 octagon cover UL Listed for inspected commercial work?
UL Listed, yes. That is the point of specifying it on commercial and institutional jobs where the inspector wants listed box components on every closure, and it is the same listing basis a facility would standardize on across a building.
4) Should I use a flat cover or a raised cover on my 4 inch octagon box?
Use the flat 724 when the box is flush with the finished surface and you just need a clean, low-profile close-out with an access point at center. A raised or extension ring is what you want when the box is set back behind drywall or you need extra box volume for conductors. The 724 adds no depth, so it will not bring a recessed box out to the finished wall or ceiling.
5) Can the RACO 724 be used on a retrofit, or is it only for new construction?
Both. The straightforward flat profile with the center knockout installs the same way on a new rough-in as it does on an existing box during maintenance or a retrofit, which is why property managers and MRO buyers keep them on the shelf for junction box close-outs.
6) What is the exact manufacturer part number for the RACO octagon flat cover with a center knockout?
The part number is RACO 724. It is a single-model item, so there is no finish or size choice to specify when ordering.
