RACO RACO262 – Frequently Asked Questions

1) Will the RACO 262 extension ring fit a standard 4-11/16 in. square box?
Yes. The RACO 262 is sized to stack directly onto an existing 4-11/16 in. square box. It has no bracket, so it mounts to the box ears rather than to framing, and it adds 2-1/8 in. of depth on top of whatever the existing box already holds.
2) How much depth does the RACO 262 add to an existing junction box?
2-1/8 in. That extra depth is what you use when conductors, splices, or a device body won't fit the original box, or when the wall finish has pushed the box too far back from the surface.
3) What size conduit can I bring into the RACO 262 extension ring?
Eight 1/2 in. and four 3/4 in. knockouts, so the ring takes 1/2 in. and 3/4 in. trade size conduit connectors. That's usually the real reason to add this ring, not depth: it gives you twelve more possible entries at one location when the original box is out of openings.
4) Can a Steel City SBEX switch box extension be used in place of the RACO 262 extension ring?
No. The RACO 262 is a 4-11/16 in. square extension ring, 2-1/8 in. deep, that stacks onto an existing 4-11/16 in. square box, with eight 1/2 in. and four 3/4 in. knockouts for conduit. The Steel City SBEX is an adjustable 1-gang switch box extension of 3.5 cu. in. in pre-galvanized steel, sized for a single-gang switch box opening. The two cover different box footprints, so the SBEX will not land on a 4-11/16 in. square box.
5) Is the RACO 262 approved for commercial and industrial conduit work?
It's cULus Listed, which covers both the US and Canadian listings, and it's built for conduit wiring systems rather than NM cable work. That's the combination an inspector looks for on commercial and industrial raceway installs.
6) Is an extension ring the right fix, or should I replace the box with a deeper one?
An extension ring is the right call when the existing 4-11/16 in. square box is already set in the wall and wired. You keep the box, stack the 262 on it, and gain 2-1/8 in. of volume plus twelve more knockouts without pulling conductors or re-mounting. Replacing the box only makes sense if it's damaged or you need a bracket-mounted box tied to studs, since the 262 has no bracket of its own.
7) Do I need a cover or anything else to finish an install using the RACO 262?
The 262 is the ring by itself. Once it's stacked on the existing 4-11/16 in. square box you still need a cover or device ring to close the opening, plus connectors matched to the 1/2 in. or 3/4 in. knockouts you punch. No mounting bracket is supplied, since it fastens to the box below it.
8) Which extension is built for conduit entries rather than just added volume?
The RACO 262 is specified for conduit wiring systems and carries eight 1/2 in. and four 3/4 in. knockouts, so additional raceway can land in the extension itself; it is drawn steel, one-piece, and cULus Listed. The Steel City SBEX is described as an adjustable 1-gang switch box extension of 3.5 cu. in. in pre-galvanized steel, which addresses box volume at a single-gang device location.
9) What does drawn steel construction mean on the RACO 262, and does it matter in the field?
Drawn means the body is formed from one piece of steel with no welded seams. On a ring that gets fastened, re-fastened, and sometimes pried during remodel work, a one-piece body holds its shape better than a welded corner. The 262 is a drawn steel box in the 4-11/16 in. square size.
