Middle Atlantic Alum Duplex Recept Plate - 828R-TCAL

Middle Atlantic 828R-TCAL Aluminum Duplex Receptacle Cover Plate

Overview

The 828R-TCAL is a slim aluminum cover plate designed for the Middle Atlantic OmniBox rectangular concrete floor box series. At just 0.25 in tall and 3.25 in wide, it provides a flush, low-profile finish for duplex receptacle cutouts in commercial flooring applications — common in conference rooms, open office deployments, data centers, and integration bays where floor boxes deliver power to rack equipment or AV infrastructure. TAA compliance makes it a viable option for government and federally funded projects requiring domestic procurement standards. If you're sourcing Middle Atlantic floor box components for a structured installation, this plate pairs directly with the OmniBox rectangular series.

Compatibility

The 828R-TCAL is engineered specifically for the Middle Atlantic OmniBox rectangular floor box line — the duplex cover plate configuration fits the rectangular OmniBox series accepting standard duplex receptacle inserts. Verify your floor box model accepts the rectangular duplex cover plate format before ordering. It is not a universal fit across competing floor box brands. For integrators building out rack and infrastructure accessories in concrete floor installations, confirm the OmniBox series model number against Middle Atlantic's floor box compatibility matrix. If your installation calls for a different outlet configuration — such as single or quad receptacle formats — alternative cover plate configurations in the OmniBox line may be required. This plate is not rated for outdoor or wet-location use; keep it to dry, finished commercial interior floors.

Installation Notes

The 828R-TCAL measures 3.25 in (W) × 4.25 in (D) × 0.25 in (H) — depth here reflects the plate's footprint relative to the floor box opening, not protrusion above the floor surface. The aluminum construction keeps the plate rigid under foot traffic without adding meaningful height above the finished floor. No tools or torque specs are specified in manufacturer documentation for the cover plate itself; fastening hardware and torque requirements are governed by the floor box unit it mounts to. Confirm floor box depth and receptacle module clearance before installing.
