Middle Atlantic Locking NIPPLE-2IN IPS-1 - 1124L-2

Middle Atlantic 1124L-2 Locking Nipple 2-Inch IPS In-Floor Service Fitting

Overview

The Middle Atlantic 1124L-2 is a 2-inch (50.8 mm) IPS locking nipple designed for in-floor service fitting applications where conduit terminations need a secure, locked connection at the floor level. The 1124L-2 addresses a common installation problem: preventing conduit nipples from backing out of floor boxes or service fittings under vibration, foot traffic, or repeated access — keeping cable management tidy and the termination point mechanically stable. This fitting is TAA compliant, making it a straightforward specification choice for government facilities, federal projects, and institutional deployments with domestic-sourcing requirements. It belongs to the Middle Atlantic 1124L-525 series locking nipple family, designed for their in-floor raceway and service fitting systems.

Compatibility

The 1124L-2 is sized for 2-inch IPS conduit and is part of the Middle Atlantic 1124L-525 series. It is intended for use with Middle Atlantic in-floor service fitting boxes and floor monuments that accept standard 2-inch IPS threaded entries. For installations using smaller or larger conduit trade sizes, verify the matching 1124L series variant — the series covers multiple diameters, and selecting the wrong size is the most common ordering error on multi-conduit floor box builds. If you are building out a complete cable management infrastructure or pairing with a PoE switch deployment that routes cabling through in-floor systems, confirm the floor box knockout or hub size matches the 2-inch IPS thread before ordering.
