Middle Atlantic 3-GANG Carpet & Tile Flange BK - 837TCAL-BK

Middle Atlantic 837TCAL-BK 3-Gang Carpet & Tile Flange — Black

Overview

The Middle Atlantic 837TCAL-BK is a 3-gang carpet and tile flange designed to finish floor box installations in commercial environments where a clean, flush surface transition is required. This black flange provides the trim interface between a Middle Atlantic floor box and finished flooring — carpet, tile, or hard surface — keeping cable access points professional and protected in open-plan offices, conference rooms, and AV integration projects. The 837TCAL-BK is TAA-compliant, making it a viable choice for government and federally funded installations with domestic sourcing requirements.

Compatibility

The 837TCAL-BK is designed for use with Middle Atlantic 3-gang floor box systems in the 837 series. It is intended for carpet and tile floor applications where the flange sits flush against finished flooring surfaces. Verify your floor box model accepts a 3-gang flange configuration before ordering — this flange does not adapt to single-gang or 2-gang openings. For AV and structured cabling deployments, confirm the floor box depth and rough-in dimensions match the 837-series footprint. If your installation uses a different color scheme, Middle Atlantic offers this flange in alternate finishes — the BK suffix designates black.

Installation Notes

Shipping dimensions are 10.5" x 16" x 0.63" (266.7 x 406.4 x 16.1 mm) — the flange itself is a low-profile trim piece. Installation requires the floor box to be set and leveled at finish-floor height prior to flange attachment; the flange is a finish trim component, not a structural element. Coordinate floor box rough-in with the AV accessories and cable management plan before concrete or subfloor work is complete, as correcting depth after the fact is costly. No special tooling is specified beyond standard installation hardware for the 837-series floor box.
