Middle Atlantic 828TAL 2-Gang Aluminum Tile Flange
Overview
The Middle Atlantic 828TAL is a 2-gang aluminum tile flange designed for flush-mount integration with concrete floor box installations. At 3.25 in wide × 4.25 in deep × 0.25 in tall, the 828TAL sits nearly flush with the finished floor surface — the low 0.25 in profile keeps the transition clean underfoot and minimizes trip hazard in high-traffic areas like conference rooms, trading floors, and AV-equipped classrooms. This flange provides the trim ring that finishes the opening between a floor box and the surrounding tile, hardwood, or polished concrete surface, giving the installation a professional edge rather than an exposed cutout.
Compatibility
The 828TAL is part of Middle Atlantic's concrete floor box accessory line, sourced through the Legrand AV infrastructure portfolio. It is sized for 2-gang floor box openings and pairs with compatible Middle Atlantic and Legrand concrete floor box bodies designed around the standard 2-gang footprint. Verify your floor box model's flange specification before ordering — not all Middle Atlantic floor box variants use the same flange dimensions. This flange is not TAA compliant, so confirm procurement requirements before specifying it on federal or GSA projects.
Installation Notes
The 0.25 in height is the critical fit dimension: the finished floor material (tile, stone, wood) must bring the surrounding surface level with or slightly above the box body so the flange seats flush. Measure finish floor thickness before cutting — a flange that sits proud of the finished floor will not lie flat. The aluminum construction handles normal foot traffic and rolling loads in typical commercial environments. No special tooling is specified beyond standard installation hardware for the host floor box body.
