Middle Atlantic Brass Dplx Recept PLT OMB - 828R

Middle Atlantic 828R Brass Duplex Receptacle Cover Plate

Overview

The Middle Atlantic 828R is a rectangular brass duplex receptacle cover plate designed for the OmniBox concrete floor box system. At 3.25 in wide × 4.25 in deep × 0.25 in tall, the 828R sits nearly flush with the floor surface — keeping the finished appearance clean in commercial installations where exposed hardware is a liability. This cover plate is the correct choice when a duplex power outlet is the sole interface needed at a floor-box location, such as AV equipment staging areas, boardrooms, or rack-adjacent floor utility zones.

Compatibility

The 828R is designed for Middle Atlantic's OmniBox rectangular concrete floor box series. Verify your floor box is the rectangular OmniBox variant before ordering — Middle Atlantic's round floor box line uses different cover plate geometry and the 828R will not fit. This plate accommodates a standard duplex receptacle insert; confirm your receptacle module matches the OmniBox rectangular opening dimensions (3.25 in × 4.25 in) prior to installation. The brass finish is suited for environments where a durable, corrosion-resistant surface material is specified — common in high-traffic commercial flooring installations.

Installation Notes

The 828R installs directly onto the OmniBox rectangular floor box with a finished height of only 0.25 in above the floor plane — verify local ADA and flooring-transition requirements if the installation is in a pedestrian path. TAA compliance is not applicable for this part; confirm project procurement requirements before specifying on government or federally-funded builds where TAA compliance is mandated.
