Pass & Seymour S1-18-W – Frequently Asked Questions

1) Can the Pass & Seymour S118W be installed in a finished wall without opening up the drywall?
That is exactly what it is built for. The S118W is an old work box, so it drops into a cut opening in an existing wall and anchors with a metal swing bracket rather than nailing to a stud. No framing work and no oversized opening needed, which is why it shows up on remodel and retrofit jobs.
2) What wall thickness does the swing bracket on the S118W old work box handle?
The metal swing bracket adjusts from 1 1/4 inch down to 1/8 inch, so it clamps onto anything in that range of finished wall material. Standard 1/2 inch and 5/8 inch drywall both sit inside that window, as does drywall over an old plaster or panel layer.
3) Do I need to add cable clamps to the Pass & Seymour S118W?
No separate clamps required. The box has 2 Auto/Clamps on each end, so cable lands and holds without extra hardware in the can.
4) What is the Quick/Click feature on the S118W box actually doing?
Quick/Click is the device-mounting system: it secures the switch or receptacle into the box quickly instead of relying on a slow screw-thread engagement. Paired with the anti-strip design, the mounting points do not strip when a device screw gets over-torqued, so you are not fishing out a ruined box after a heavy-handed drill driver.
5) Is the S118W a metal box or plastic, and does that affect grounding?
The body is Grey thermoplastic, a nonconductive housing, so there is no metallic box to bond. Only the swing bracket is metal. Your equipment ground goes to the device and to the grounding conductors in the box, the way it does with any nonmetallic old work box.
6) What part number do I order for the Pass & Seymour Quick/Click old work box?
Order it as Pass & Seymour S118W, catalog number S1-18-W. It is made in the United States. One model, one configuration, in Grey.
7) Where do I find the manufacturer spec sheet for the S118W?
Pass & Seymour publishes a spec sheet PDF for the S118W, and it is linked in the product specs under PDF: Spec Sheet. That is the document to attach when a spec package needs the manufacturer data.
