Middle Atlantic Rect Duplx Recept Plt-bk - 828R-TCAL-BK

Middle Atlantic 828R-TCAL-BK Rectangular Duplex Receptacle Cover Plate

Overview

The 828R-TCAL-BK is a black rectangular duplex receptacle cover plate designed for Middle Atlantic's OmniBox concrete floor box system. At 3.25 in wide × 0.25 in tall with a 4.25 in depth dimension, this plate drops into the OmniBox rectangular opening and provides a finished, low-profile surface for duplex outlet access in floor-level power distribution installations — the kind of clean, unobtrusive power access point common in conference rooms, operations centers, and open-plan commercial spaces where floor boxes feed AV and security equipment. TAA-compliant construction makes it suitable for federal, government, and GSA-schedule deployments where country-of-origin requirements apply.

Compatibility

Designed specifically for the Middle Atlantic OmniBox rectangular concrete floor box series. Verify your floor box model accepts a rectangular duplex cover configuration before ordering — Middle Atlantic's floor box accessories line includes multiple cover plate formats (single, duplex, data, combination) and this plate is specifically the rectangular duplex receptacle variant in black. Not interchangeable with round OmniBox covers or square-format floor box openings. Color: black — confirm your installation's finish requirement if other OmniBox components are specified in a different color family.

Installation Notes

The 0.25 in plate height sits nearly flush with the finished floor surface, which matters in high-traffic areas where trip hazard and ADA compliance are considerations — verify your floor box rough-in depth accommodates the 4.25 in depth spec before the slab is poured or the box is set. Install the receptacle into the box before snapping or securing the cover plate; no special tooling is indicated beyond standard electrical finish work. Confirm receptacle yoke dimensions match the duplex opening cutout in this cover plate prior to installation.
