Pass & Seymour S120HGAC 4-in Round Ceiling Box, Noryl Thermoplastic

UL Listed for fan and fixture support, this box is built for durable, code-compliant overhead installations where reliability matters most. Molded-in Auto/Clamp cable clamps hold wire securely in the box, while a depth-mounting gauge at the bottom of the bracket helps installers align the box at the proper depth relative to the finished ceiling.

Pass & Seymour S1-20-HGAC – Frequently Asked Questions

1) Can the Pass & Seymour S120HGAC ceiling box support a ceiling fan, or is it fixture-only?
The S120HGAC 4-inch round ceiling box is UL Listed for fan and fixture support, so it can carry a ceiling fan as well as a lighting fixture. That listing is what separates a fan-rated box from an ordinary lighting outlet box, and it is why this one gets specified on overhead openings where a fan may go in later.
2) Is the S120HGAC a metal box or plastic, and does that affect bonding?
It is molded from impact-resistant Noryl thermoplastic in black, not metal. The body is non-conductive, so there is no box to bond the way you would with a steel box; grounding is handled through the conductors and fixture ground. The plastic also takes impact during rough-in without denting or cracking.
3) Is this ceiling box for new construction rough-in or for retrofit into an existing ceiling?
The S120HGAC is a bracket-mounted new-construction box, intended to be fastened to framing during electrical rough-in before the ceiling is closed. It also gets used for outlet box replacement in ceilings and for renovation work where the framing is accessible. For a cut-in into finished drywall with no access above, you want an old-work fan-rated box or a retrofit brace bar instead.
4) Do I need separate cable clamps or connectors with this ceiling box?
No separate clamps are needed. Auto/Clamp cable clamps are molded directly into the S120HGAC body and grip the cable as it enters, so nonmetallic cable is secured without adding connectors to the box.
5) How do I set this box at the right depth for a finished ceiling?
There is a depth-mounting gauge at the bottom of the mounting bracket on the S120HGAC. You set the box against the joist using that gauge so the box edge lands correctly relative to the finished ceiling surface, which keeps the fixture canopy sitting flat instead of standing proud of the drywall.
6) Does the Pass & Seymour S120HGAC carry a UL Listing?
Yes, it is UL Listed, and additionally UL Listed for fan and fixture support. For an inspector looking at an overhead fan outlet, that fan-and-fixture listing is the line item that matters.
7) Will a standard 4-inch round fixture canopy or fan bracket land on this box?
Yes. The S120HGAC is a 4-inch round trade-size ceiling box, the standard size fan brackets and fixture canopies are built to cover, so a typical fan mounting plate or lighting canopy mounts to it without an adapter or extension ring.
8) What is the correct part number to order this 4-inch round fan-rated ceiling box?
Order Pass & Seymour model S120HGAC, manufacturer part number S1-20-HGAC. It is a single configuration, black Noryl, 4-inch round, made in the United States.
