Pass & Seymour S122-W – Frequently Asked Questions

1) Will the Pass & Seymour S122W work in an existing finished wall, or is it a new-construction box?
The S122W is an old-work box, meant to go into a wall that is already closed up. It mounts with an adjustable swing bracket that grips the back of the wall, so you cut the opening, feed the cable, and tighten the bracket without opening up drywall or plaster to reach a stud. For new construction where you can nail to framing, you want a new-work box instead.
2) What wall thickness does the swing bracket on the S122W adjust to?
The swing bracket adjusts from 1 1/4 inch down to 1/8 inch, which covers the usual range of finished wall materials you run into on retrofit work, from thin paneling up to thick plaster or double-layer drywall.
3) Do I need to add cable clamps to the S122W old work box?
No separate clamps needed. The box has integrated Auto/Clamps on each end, so the cable is secured by the box itself. That is one less part to carry and one less thing to leave out on an inspection.
4) Is the Pass & Seymour S122W UL listed for commercial work?
It carries both UL Listed and cULus Listed certification, and it is RoHS compliant. The cULus listing means it is accepted for Canadian installations as well as US.
5) What is the Quick/Click feature on the S122W and does it change how I mount a device?
Quick/Click is the device-mounting system built into the box: the switch or receptacle seats and secures quickly rather than needing the screws run all the way down blind. The mounting points also resist stripping if you over-torque them, which is the usual failure on plastic boxes when a device gets snugged hard against an uneven wall.
6) Is the S122W metal or plastic, and does that matter for grounding?
It is molded thermoplastic in gray, not metal. A nonmetallic box is not part of the ground path, so your equipment ground has to be carried on the wire and landed on the device. If your job spec calls for a metallic box, this is not the one.
7) Can I use the S122W for both switches and receptacles, or just one?
Both. It is a single-gang switch/outlet box, so it takes a switch or a receptacle equally, which is why it works well for property managers standardizing on one box for device replacements across finished walls.
8) What is the exact part number and origin for the Pass & Seymour deep old work box in gray?
Order it as Pass & Seymour S122-W, sold as the S122W model. It is made in the United States.
