Middle Atlantic 1124L-11/4 Locking Nipple 1-1/4 In.
Overview
The Middle Atlantic 1124L-11/4 is a 1.25 in. (31.8 mm) diameter locking nipple designed for in-floor service fitting installations. This fitting secures conduit or service assembly connections in floor box and in-floor raceway systems where vibration, foot traffic, or repeated access cycles could otherwise loosen standard threaded fittings over time. TAA-compliant, making it a valid choice for federally funded or government facility infrastructure projects. If you are specifying Middle Atlantic in-floor systems for commercial or government spaces, the 1124L-11/4 addresses the common problem of fittings backing out under regular use.
Compatibility
Designed for the Middle Atlantic 1124L-525 series locking nipple product line, compatible with in-floor service fitting assemblies that accept a 1-1/4 in. threaded nipple connection. Verify thread pitch and fitting recess depth against your specific floor box or raceway infrastructure before ordering — the 1.25 in. nominal diameter must match the receiver on your installed floor box or monument fitting. Consult the Middle Atlantic accessories catalog for companion fittings in the same 1124L series if you need alternate diameter variants for the same installation.
