Steel City 68 P Non-Metallic Flush Floor Box, PVC

The 68 P is a 100 cubic inch box, which is a lot of fill for a floor application and leaves room for multiple circuits or a combination power and low-voltage service. For comparison, the Wiremold 880W1 steel 1-gang floor box is 53 cubic inches, so the 68 P roughly doubles it if your conductor count is driving the box choice.

It is a non-metallic PVC box, grey in color. Because the enclosure is not conductive, it does not serve as part of the equipment grounding path the way a steel floor box can, so you carry an equipment grounding conductor to the device and bond at the device or the service fitting. PVC also means no corrosion concerns in a slab pour.

No. The 68 P ships with zero knockouts, so the installer makes the entries. With a PVC body that means field-cutting or drilling the hubs you need for your raceway, rather than punching a stamped opening like you would on a steel box.

The Pass & Seymour TM1542 series floor box is also a PVC floor box, making it the closest non-metallic counterpart to the Steel City 68 P, which is a PVC flush service floor box. Both avoid steel, so neither needs the corrosion protection a steel box in a slab pour would call for. Confirm the TM1542 volume suits your conductor fill before swapping, since the 68 P offers 100 cubic inches.

If your spec or inspector calls for a metallic box, the Wiremold 880W1 is a steel 1-gang floor box at 53 cubic inches, and the Wiremold 885B is a shallow steel single service box in the 880 series. The Steel City 68 P is PVC at 100 cubic inches, so it carries more wiring volume but will not satisfy a drawing that requires a metal box or a metallic equipment grounding path through the enclosure.

For a thin pour or a wood floor with limited depth, the Wiremold 880M1 OmniBox single gang shallow steel floor box and the Wiremold 885B shallow steel single service floor box are both built as shallow boxes. The Steel City 68 P is a 100 cubic inch PVC box, so it needs correspondingly more depth; the shallow steel options trade wiring volume for a lower profile.

Flush service. The 68 P is set so the service fitting finishes level with the floor, which is what you want in a lobby, classroom, or open office where a raised fitting is a trip hazard or a furniture conflict.

PVC like the Steel City 68 P is the usual pick for concrete because it will not rust in the slab and it pairs naturally with PVC conduit runs. Steel boxes, such as the Wiremold 880 Series shallow single-service box or the OmniBox 880M1, are the choice when you need the enclosure itself in the grounding path or you are working in a shallow or wood-frame floor rather than a deep pour. If you want another PVC option, the Pass & Seymour TM1542 Series floor box is also non-metallic.

Go to a shallow box. The Wiremold 885B is a shallow steel single-service floor box and the Wiremold 880M1 OmniBox is a single-gang shallow steel box, both intended for floors that will not take a deep 100 cubic inch enclosure. You give up fill capacity in the trade, so count your conductors before you switch.

The 68 P is the box itself, a flush-service non-metallic enclosure. The cover plate or service fitting and the device are separate items selected to match the finish and the service you are bringing up, so plan on ordering those alongside it.

No. The 880W1 is a steel 1-gang floor box with 53 cubic inches of volume, while the Steel City 68 P is a PVC flush service box with 100 cubic inches. Different material and roughly half the volume means different conduit entry and fill calculations, so treat it as a separate box selection rather than a like-for-like swap in an existing opening.

The Steel City 68 P carries UL file E11461 and is a PVC flush service floor box with 100 cubic inches of volume, supplied each. The Wiremold comparables are steel: the 885B in the 880 series as a shallow single service box and the 880M1 in the OmniBox series as a single gang shallow box. For standardizing across a facility, the decision is usually material and depth rather than service configuration.

Each. One 68 P box per unit, so order the count you need opening by opening rather than by the box.
