Middle Atlantic 880CS2-NA 2-Gang Cast Iron Concrete Floor Box
Overview
The Middle Atlantic 880CS2-NA is a 2-gang cast iron floor box from the OmniBox Series, designed for in-floor device mounting in concrete slab construction. If you're running AV, security, or low-voltage wiring through a concrete floor and need a code-compliant, permanent enclosure for outlet or data faceplates, the 880CS2-NA provides the structural housing to do it right. TAA compliant, making it a valid choice for government, federal, and GSA-schedule projects where country-of-origin compliance is required.
Compatibility
The 880CS2-NA is part of Middle Atlantic's OmniBox Series concrete floor box line. It accepts standard 2-gang device configurations — compatible with typical duplex outlet plates, keystone inserts, or low-voltage brackets that fit a 2-gang opening. Verify specific faceplate and mud ring compatibility against the OmniBox Series accessory lineup before ordering, as finish rings and covers are typically sold separately. Suitable for integration into AV infrastructure, structured cabling, and security system wiring runs where conduit terminates below finished floor level.
Installation Notes
Designed for installation in concrete floors during the pour or cut-in after cure — confirm your specific installation method (pre-pour vs. saw-cut) against the OmniBox Series installation guide, as box preparation and conduit entry approach differ. Shipping dimensions are 9.63
