Middle Atlantic 828R-TCAL-NK Rectangular Duplex Receptacle Cover Plate
Overview
The 828R-TCAL-NK is a nickel-finish rectangular duplex receptacle cover plate designed for Middle Atlantic OmniBox concrete floor box systems. At 3.25 in wide × 4.25 in deep × 0.25 in tall, this low-profile plate closes out a duplex power outlet position in a flush floor box installation — the finishing component that keeps a rack room or AV-integrated space looking clean and code-compliant once conduit and receptacles are set. TAA compliant, making it suitable for government and federally funded projects where trade agreement sourcing is a contracting requirement.
Compatibility
Designed for the Middle Atlantic OmniBox rectangular concrete floor box series. Fits the rectangular duplex cutout position within OmniBox assemblies — confirm your floor box model accepts a standard rectangular duplex cover plate before ordering, as OmniBox configurations vary by insert layout. The nickel (NK) finish coordinates with standard brushed nickel hardware commonly specified in commercial AV and security infrastructure builds. If your floor box uses a different finish family or a non-rectangular duplex cutout, verify the cover plate part number against your specific OmniBox configuration.
Installation Notes
At 0.25 in tall, the plate sits flush or near-flush with the floor box frame — verify the installed receptacle depth does not cause the cover to bow or gap before fastening. No special tooling is called out in the available evidence beyond standard flathead or Phillips hardware typical of floor box cover installations.
