Wiremold 885B 880 Series Shallow Steel Single Service Floor Box

The Wiremold 885B is a stamped steel, 1-gang shallow above-grade single service concrete floor box from the 880 Series™ family, engineered to deliver power, data, or communications access at floor level in commercial and institutional spaces. Sized at 4-13/16-Inch x 4-13/16-Inch x 2-7/16-Inch with 29.5-Cubic-Inch of usable capacity, this shallow-profile box is designed for installations where floor depth is limited, such as slab-on-grade or shallow poured concrete applications. Built from durable stamped steel, the 885B provides a rugged, code-compliant enclosure for a single device while maintaining a low-profile footprint that simplifies coordination with finished flooring and trim assemblies.

Key Features

Wiremold 885B – Frequently Asked Questions

1) Will the Wiremold 885B floor box fit in a shallow concrete slab pour?
That is what it is built for. The 885B is a shallow above-grade concrete floor box with an overall depth of 2-7/16 inches and a 4-13/16 x 4-13/16 inch footprint, so it goes in where a standard-depth box will not clear the slab. Typical use is slab-on-grade or a thin poured topping over structural deck. If you have full slab depth and want more wiring room, a deeper box is the better choice.
2) How many devices can I put in a Wiremold 885B?
One. The 885B is a 1-gang, single service box, so it carries a single receptacle, data jack, or communications device, not a power-plus-data split. If you need power and low voltage separated in the same opening, you need a two-gang or multi-service box instead.
3) Will the 885B take 880 Series covers and carpet flanges?
Yes, the 885B is part of the Wiremold 880 Series floor box platform and is dimensioned for the compatible 880 Series covers and accessories. The box ships as the enclosure only, so the cover plate, carpet or tile flange, and the device itself are separate line items you add to the order.
4) Is the Wiremold 885B rated for below-grade or on-grade in-ground use?
No. The 885B is specified as a shallow above-grade concrete floor box. For below-grade or on-grade installations where moisture and soil contact are a factor, use a box specifically rated for that service instead.
5) Is 29.5 cubic inches enough volume for a receptacle and 12 AWG conduit runs in a floor box?
The 885B gives 29.5 cubic inches of usable interior volume. Box fill under the NEC is counted per conductor by wire size plus allowances for the device and grounds, so run that calculation for your actual conductor count before you commit. For a single device fed and looped with a modest number of conductors it is workable; a heavily looped feed-through is where a shallow single-gang box runs out of room.
6) Steel or PVC floor box for a concrete pour?
The 885B is stamped steel, which gives it the rigidity to hold shape under concrete placement and foot traffic once the floor is finished. If you want a nonmetallic body instead, for example where you prefer no metal in the pour, ZenSupply carries the Pass & Seymour TM1542 Series floor box in PVC. Steel also lets you bond the enclosure as part of the grounding path, which nonmetallic boxes do not.
7) Can I use the 885B as a retrofit replacement for an existing single-device floor outlet in a concrete floor?
It is a listed application for the box. The 885B is intended for single-device above-grade floor box retrofits as well as new concrete floor wiring, and its shallow 2-7/16 inch depth is what makes it work in an existing opening where you cannot chase deeper into the slab. Verify your existing core or chase accepts the 4-13/16 inch square footprint.
8) What does a Wiremold 885B floor box weigh and what finish is the steel?
Each 885B weighs 1.918 lb and the steel body is silver in appearance. It is a light single-gang stamped enclosure, so one person sets and ties it off to the deck or rebar without help. Manufactured in Mexico.
