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

Middle Atlantic 1124-1 Locking Nipple 1-Inch IPS Service Fitting

Overview

The Middle Atlantic 1124-1 is a 1-inch IPS locking nipple designed for in-floor service fitting installations. Part of the 1124-525 series, this fitting secures conduit or raceway connections in floor monument and service outlet configurations where vibration or foot traffic could otherwise loosen standard threaded fittings. At 1 inch (25.4 mm) diameter, the 1124-1 fits the most common intermediate conduit size used in commercial AV and security infrastructure runs. TAA compliance makes it a straightforward procurement for federal projects and government-funded installations subject to trade agreement requirements.

Compatibility

Designed for use within the Middle Atlantic in-floor systems product line, specifically the 1124-525 series locking nipple family. Fits standard 1-inch IPS threaded fittings used in in-floor service fittings and floor monument enclosures. Compatible with 1-inch IPS conduit and raceway terminations common in commercial building infrastructure. Confirm thread engagement depth against your specific floor box or monument before ordering — the 1124-1 is sized for 1-inch IPS and will not fit 1/2-inch or 3/4-inch openings.

Installation Notes

The locking design requires the fitting to be threaded fully into the receiving female IPS opening before engaging the locking mechanism — do not overtighten prior to locking, as this can prevent the lock from seating correctly. Verify the floor box knockout or monument opening is cleared of burrs before installation to protect thread integrity on both the nipple and the receiving fitting.
