Middle Atlantic STL SHL FLR BX 2-GANG OMB - 880M2

Middle Atlantic 880M2 Shallow Steel 2-Gang Floor Box

Overview

The Middle Atlantic 880M2 is a shallow 2-gang steel floor box from the OmniBox series, designed for concrete floor installations where low-profile in-floor cable termination and device mounting are required. At 2.5 in tall and 9.5 in deep, the 880M2 fits installations where slab depth is limited — a common constraint in commercial renovations, raised access floors, and conference room buildouts. The 2-gang configuration accommodates dual device inserts side by side, supporting a mix of power, data, and AV connectivity in a single floor penetration. TAA compliance makes the 880M2 suitable for federal, government, and GSA-schedule projects where country-of-origin sourcing requirements apply. The 7 in width keeps the footprint compact while still fitting standard 2-gang insert hardware from the Middle Atlantic OmniBox line.

Compatibility

The 880M2 is part of Middle Atlantic's OmniBox Series shallow concrete floor boxes. It accepts standard 2-gang device inserts compatible with the OmniBox platform — including power outlet inserts, keystone data inserts, and AV connection plates sold separately within the series. Verify insert gang count and trim ring compatibility with Middle Atlantic's OmniBox accessory catalog before ordering, as the shallow 2.5 in height constrains which insert modules will seat correctly. For deployments integrating structured cabling or network infrastructure, confirm that your conduit stub-up or wire management approach accounts for the 9.5 in installation depth. This box is intended for concrete floor applications; consult Middle Atlantic's product family for raised-floor or wood-subfloor variants if your install environment differs.

Installation Notes

Installation depth requirement is 9.5 in — verify slab thickness before rough-in. The shallow 2.5 in height means standard deep-body inserts may not fit; use only OmniBox-series shallow inserts rated for this box. Confirm conduit entry knockout sizing against your local code requirements prior to pour or floor finish. TAA compliance documentation should be retained for project closeout packages on government or federally funded installations.
