Middle Atlantic Locking NIPPLE-1 1/4IN I - 1124-11/4

Middle Atlantic 1124-11/4 Locking Nipple 1-1/4 In

Overview

The Middle Atlantic 1124-11/4 is a 1-1/4 in (31.8 mm) diameter locking nipple designed for in-floor service fitting installations. This TAA-compliant hardware fitting secures conduit or service fittings in place within structured cabling and in-floor raceway systems — the right part when a standard nipple won't hold position under foot-traffic vibration or repeated access-cover removal. Specify the 1124-11/4 wherever a locking mechanism is required at the 1-1/4 in trade size.

Compatibility

Designed for use within Middle Atlantic in-floor service fitting assemblies, specifically the 1124-525 series locking nipple family. Pairs with compatible in-floor raceway service fittings and floor boxes that accept 1-1/4 in trade-size threaded connections. Confirm your floor box or fitting accepts 1-1/4 in threaded nipple before ordering — this size does not interchange with 1 in or 1-1/2 in variants in the same series. TAA compliance makes this fitting eligible for TAA-compliant infrastructure projects and GSA Schedule deployments where domestic sourcing documentation is required.
