Middle Atlantic STL DP FLR BX 2-GANG Ombx - 880S2

Middle Atlantic 880S2 STL DP Floor Box 2-Gang Omnibox

Overview

The Middle Atlantic 880S2 is a steel, in-floor junction box designed for structured AV and low-voltage installations in commercial concrete floors. The 880S2 fits 2-gang device configurations, making it a practical choice for conference rooms, boardrooms, and open office environments where power, data, or AV connectivity needs to terminate at the floor level without exposed surface raceways. At 7 in wide × 3.5 in tall × 9.5 in deep (17.8 × 8.9 × 24.1 cm), it provides enough depth to accommodate standard connectors and bend radius for low-voltage cabling without crimping conductors.

Compatibility

The 880S2 is part of Middle Atlantic's Omnibox Series steel floor box line, designed to accept compatible 2-gang inserts and cover plates within the Omnibox ecosystem. It is suited for concrete floor applications where a recessed, flush-mount box is required. Compatible inserts typically include power, USB, HDMI, and RJ-45 modules from the Omnibox accessory family — verify specific insert compatibility against the Omnibox Series configuration guide before ordering. TAA compliance makes it eligible for GSA-schedule and federal procurement projects.

Installation Notes

This box is rated for concrete floor installation. The 9.5 in depth requires adequate concrete slab thickness or a poured-in-place installation during construction — confirm pour depth before specifying on retrofit projects. The 2-gang opening accepts standard Omnibox Series faceplates and inserts; measure finished floor height to ensure the cover plate sits flush after flooring material (tile, carpet, hardwood) is applied, as finish floor thickness directly affects cover plate fit.
