RACO RACO976 – Frequently Asked Questions
1) My switch box sits too deep behind new drywall. Will a RACO 976 ring bring it flush?
That is exactly what the RACO 976 Add-a-Depth ring is for. It mounts to an installed switch box and extends the box depth forward so the opening comes flush with the finished wall surface after drywall, tile, or paneling is added. You keep the existing box and wiring in place rather than cutting it out and resetting a deeper one.
2) Is the RACO 976 the same thing as a 4 inch square to 3 inch round adapter?
No. The 976 adds depth to a switch box so the opening reaches the finished wall; it does not change the box shape or device pattern. If what you need is to convert a 4 inch square box opening to a 3 inch round pattern, that is a different part, such as the Mulberry 11214 (series CV52R3) square-to-round box adapter, sold 100 to a pack.
3) Can a Mulberry 11214 4-inch square-to-3-inch round box adapter be used instead of the RACO 976 add-a-depth ring?
No, they solve different problems. The RACO 976 Add-a-Depth Steel Switch Box Ring extends the depth of an already installed switch box so it comes flush with the finished wall after drywall, tile, or paneling is added. The Mulberry 11214 is a CV52R3 adapter that changes the opening of a 4-inch square box to a 3-inch round pattern, which is a shape and device-pattern change rather than a depth correction. If the box is set too deep behind the finish, the 976 ring is the part that addresses it; if the box opening is the wrong configuration for the device or cover being mounted, the square-to-round adapter is the one to look at.
4) Is the RACO 976 add-a-depth ring steel or plastic?
Steel. The 976 is part of RACO's steel box support product line, so it holds its shape under device screw torque and takes drywall mud and trim work without flexing like a plastic extender.
5) Can I use an add-a-depth ring on a remodel instead of replacing the existing switch box?
Yes, that is the usual reason to reach for one. The RACO 976 corrects box depth on remodel and retrofit jobs without swapping the box out, so you avoid opening the wall around the box, re-securing it to the stud, and redoing the cable terminations. It works the same way on new construction where wall finish buildup left the box set back.
6) I have a 4-inch square box that needs a round device opening, not more depth. What should I order?
For that opening, the Mulberry 11214 CV52R3 adapter is the match, since it converts a 4-inch square box to a 3-inch round pattern. The RACO 976 Add-a-Depth Steel Switch Box Ring is built for switch boxes that sit too far back from the finished wall and need their depth brought forward, so it will not change the shape of the box opening. Confirm which problem you have at the box before ordering, because the two parts are not interchangeable.
7) We buy box accessories in bulk for multifamily rough-in. How do the RACO 976 ring and the Mulberry 11214 differ in how they are packaged and used?
The RACO 976 Add-a-Depth Steel Switch Box Ring is ordered as a single model, part number 976, and is used on switch boxes that need to be brought flush with the finished wall surface during remodel, retrofit, or new construction. The Mulberry 11214 CV52R3 is supplied as a pack of 100 and performs a 4-inch square-to-3-inch round opening conversion. Crews doing depth corrections across many openings would stock the 976; crews standardizing round device openings on 4-inch square boxes would stock the Mulberry adapter.
