Cantex EZ20SB – Frequently Asked Questions

1) Will the Cantex EZ20SB mount to steel studs, or do I need a wood stud box?
The EZ20SB is built for steel stud framing. It comes with an integrated steel stud bracket, so it attaches directly to a standard steel stud framing member with no added mounting hardware. If you are roughing in on wood studs, this is the wrong bracket style for that application.
2) Is 20 cubic inches enough box fill for a single receptacle with a couple of splices?
The EZ20SB gives you 20 cubic inches in a 1-gang box, which is on the roomier end for single-gang work. That volume is there to take the device, the conductors and pigtail splices without crowding. Count your conductors against the fill allowances in your local code before you commit, since the device, clamps and grounds all draw against that 20 cubic inches.
3) What should I use instead of the Cantex EZ20SB when the device needs to mount in an exposed outdoor location?
The Cantex EZ20SB is a non-metallic 1-gang box with an integrated steel stud bracket, built for rough-in on steel stud framing behind finished wall surfaces. For an exposed surface-mounted run fed by conduit, the Thomas & Betts Red-Dot 2IH3-2 is a 2-gang RT box with three 3/4-inch hubs, so the raceway threads directly into the body instead of entering a bracketed wall box.
4) Is a 4-inch square box an equivalent to the Cantex EZ20SB for a single switch?
They solve the opening differently. The EZ20SB is a 1-gang box measuring 3-5/8 inch x 2-1/4 inch x 3-1/8 inch with 20 cubic inches of volume and a bracket for steel stud framing. The RACO 232MS is a 4 inch square welded box 2-1/8 inch deep in the STAB-iT Series; a square box takes a single device only with a mud ring or device cover, and it is not supplied with a steel stud bracket.
5) What are the actual dimensions of the Cantex EZ20SB box?
It measures 3-5/8 x 2-1/4 x 3-1/8 inches, a standard single-gang footprint, so a normal 1-gang switch or receptacle plate covers it and a straight blade device screws in on the usual centers.
6) Is the EZ20SB metal or plastic, and will it corrode in a damp wall cavity?
Non-metallic housing, not steel. That resists corrosion, which is part of why it gets used for residential rough-in. Note that the bracket is the steel part; the box body itself carries no metal, so there is no metal raceway bonding path through the box and your equipment ground has to be carried in the cable.
7) I need a 2-gang box with conduit hubs instead of a single-gang stud box. What else is there?
The EZ20SB is single-gang only, so for two devices look elsewhere. The Thomas and Betts Red-Dot 2IH3-2 is a 2-gang RT box with three 3/4 inch hubs, sold in packs of 100, which suits exposed conduit work rather than in-wall stud mounting. For a larger junction or multi-device box, the RACO 232MS is a 4 inch square welded box, 2-1/8 inches deep, rated 600V.
8) Can I use the Cantex EZ20SB on a remodel, or is it new construction only?
Both. It is intended for rough-in on steel stud framing in new construction and in remodel or retrofit work where the studs are exposed. Because it mounts by a bracket to the stud face, you need access to the framing, so it is not an old-work box for cutting into finished drywall.
9) I need two devices at one location - does the Cantex EZ20SB cover that?
No. The Cantex EZ20SB is a 1-gang configuration intended for a single receptacle, switch, or straight blade device. For a two-device location, the Thomas & Betts Red-Dot 2IH3-2 is a 2-gang box, though it is a hubbed RT box rather than a steel stud bracketed wall box, so the wiring method has to suit conduit entry.
10) What is the Cantex part number to order a 1-gang steel stud box?
Order Cantex EZ20SB. That is the manufacturer part number for the 1-gang EZ Box non-metallic steel stud box with the bracket attached.
11) What devices fit in the EZ20SB, switches and outlets both?
Single receptacles, switches and other straight blade devices all fit the 1-gang EZ20SB. It is a general-purpose device box for switch and receptacle rough-in rather than a box prepped for a specialty or heavy device.
12) Which box should I standardize on for a metal-framed tenant build-out where boxes are bought by the case?
For single-gang devices in steel stud partitions, the Cantex EZ20SB is the direct fit - non-metallic body, 20 cubic inch volume, and the steel stud bracket already attached. Where the same job has exposed conduit work, the Thomas & Betts Red-Dot 2IH3-2 is offered in a pack of 100 as a 2-gang hubbed box, so a facility can carry one bracketed wall box and one hubbed box rather than several of each.
