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

Overview

The Middle Atlantic 828PR-BLK is a black polycarbonate rectangular duplex cover plate designed for the Middle Atlantic OmniBox concrete floor box system. At 3.25 in wide × 4.25 in deep × 0.25 in tall, the 828PR-BLK provides a flush, low-profile finish over duplex outlet cutouts — keeping cable and power access points protected and visually clean in commercial flooring installations. TAA-compliant construction makes it a straightforward fit for government and federally funded facility projects subject to Trade Agreements Act procurement requirements. This is a floor box cover plate — a finish component, not a powered device — so it drops directly into the accessory path for any OmniBox concrete floor box project without additional wiring or configuration.

Compatibility

Designed specifically for the Middle Atlantic OmniBox rectangular concrete floor box series. The 828PR-BLK covers duplex (two-outlet) configurations in the OmniBox platform. If your floor box installation uses a single-gang or data-only insert rather than a duplex power insert, confirm the outlet pattern matches before ordering — this plate is cut for a standard duplex outlet face. Pair with compatible floor box inserts and modules from the Middle Atlantic OmniBox accessory line to complete the assembly. For AV and security infrastructure projects requiring structured cabling coordination, this plate integrates into broader cable management planning without modification.

Installation Notes

The 0.25 in profile sits nearly flush with finished floor surfaces, reducing trip-hazard exposure in high-traffic areas. Black finish (828PR-BLK) matches standard commercial floor box color schemes — specify accordingly if the project requires a matching finish across multiple outlet positions. No tools beyond standard floor box fasteners are required for cover plate installation.
