Middle Atlantic Brass CPT FL 2-GANG Ombx - 827C

Middle Atlantic 827C Brass CPT FL 2-Gang Floor Box Flange

Overview

The Middle Atlantic 827C is a brass 2-gang flange (cover plate) designed for concrete pour-in-place floor box installations. At 6 in wide, 9.25 in deep, and just 0.63 in tall, the 827C sits flush at slab level — keeping the finished floor clean while protecting the outlet cavity below. This is the right part when you need a code-compliant, low-profile termination point for power or data runs embedded in concrete floors, typical in conference rooms, trading floors, open office builds, and AV-integrated meeting spaces. The 827C is sourced from Middle Atlantic's floor box line, part of the broader floor box and in-floor infrastructure category.

Compatibility

The 827C flange is designed for Middle Atlantic's concrete floor box series — specifically pour-in-place and after-pour concrete applications requiring a 2-gang opening. Verify the rough-in box model accepts a standard 2-gang flange footprint (6 in x 9.25 in) before ordering. This flange is not interchangeable with poke-through or wood-floor box assemblies, which use different rough-in dimensions and mounting patterns. For full AV infrastructure builds, pair with compatible power and surge protection inserts sized for 2-gang floor box cavities.

Installation Notes

The 0.63 in height profile means the flange lies nearly flush once concrete is poured and finished — factor this into your slab pour sequence so the flange surface aligns with final floor level, not sub-slab. Brass construction resists corrosion in high-traffic areas but will show wear under heavy foot traffic without a protective carpet or tile cutout surround. TAA compliance is not applicable to this SKU. Confirm local electrical code requirements for floor box cover ratings (wet/damp location designations) before specifying in exterior or high-moisture environments.
