Topaz Lighting R2242 – Frequently Asked Questions

1) Will a Topaz R2242 device ring fit a standard 4 inch square electrical box?
Yes. The Topaz R2242 is sized to mate with 4 inch square boxes, the common box used in conduit and raceway rough-in. It raises the box face and adapts the round-corner square box opening to take a 2-gang wiring device or a 2-gang cover plate.
2) What raise heights does the Topaz 4 inch square double-gang device ring come in?
Two: a 1/2 inch raise, part number R2242, and a 5/8 inch raise, part number R2243. Pick the one that brings the device face flush with your finished wall. Half inch drywall usually wants the 1/2 inch ring; 5/8 inch board or a layer of tile backer typically calls for the 5/8 inch.
3) How much cubic inch volume does the R2242 mud ring add for box fill?
5.4 cubic inches. Add that to the marked volume of the 4 inch square box when you run your NEC box fill calculation for the conductors, devices and grounds landing in that box.
4) Can I mount two receptacles or a single 2-gang plate on this Topaz ring?
Either one. The double-gang opening takes two standard wiring devices side by side, or one 2-gang cover plate over a blank or combination arrangement.
5) Do I still need a mud ring if I am mounting devices in a 4 inch square box?
Yes, if you want to land a standard 2-gang device. A 4 inch square box has its own screw pattern and a square opening, so a device ring like the Topaz R2242 is what converts it to a 2-gang device pattern and sets the face at the right depth for a flush plate. Without one there is nothing to screw a standard 2-gang plate to.
6) Which Topaz ring should I use if the box is set behind 5/8 inch drywall?
Use the R2243, the 5/8 inch raise. The 1/2 inch R2242 would leave the device recessed behind the finished surface on 5/8 inch board.
7) Is a galvanized steel device ring suitable for damp commercial or industrial work?
The ring is galvanized steel, which gives it corrosion resistance and mechanical strength for commercial and industrial box installations as well as residential rough-in. It is a steel ring for steel boxes, not a plastic or nonmetallic part.
