Middle Atlantic Polycarbonate Dplx PLT OM - 828PR-BRN

Middle Atlantic 828PR-BRN Polycarbonate Duplex Cover Plate for OmniBox Floor Boxes

Overview

The Middle Atlantic 828PR-BRN is a brown polycarbonate duplex cover plate designed for the OmniBox rectangular concrete floor box system. At 3.25 in wide × 4.25 in deep × 0.25 in tall, the 828PR-BRN sits nearly flush with the floor surface — keeping the outlet accessible without creating a trip hazard or protruding lip that collects debris on a finished concrete slab. TAA compliance makes it a straightforward choice for federal facilities, GSA-schedule projects, or any government-funded installation requiring domestic trade agreement sourcing. The brown finish integrates cleanly into wood-toned flooring environments where a standard white or gray plate would stand out.

Compatibility

This cover plate is designed for use with the Middle Atlantic OmniBox rectangular plastic duplex floor box series. Confirm your floor box model accepts a standard duplex plate configuration — the 3.25 in × 4.25 in footprint is specific to the OmniBox rectangular form factor. It is not interchangeable with round floor box covers or with non-OmniBox floor box brands. For other finish colors in the same plate series, verify the Middle Atlantic Middle Atlantic floor box accessories line for matching SKUs across white, ivory, and black options.

Installation Notes

The 0.25 in height profile means the plate is designed to seat directly into the floor box bezel with minimal surface projection — verify the concrete pour depth and floor box rim are flush before final installation, as any recess or crown in the slab surface will affect how the plate seats and whether it remains level. No special tools are specified beyond standard fasteners included with the parent floor box assembly. This plate does not include a floor box unit; the floor box must be ordered separately from the floor box category.
