L H Dottie Co NSR12L Nylon Strain Relief Connector

Product Description

The L H Dottie Co NSR12L is a 1/2 inch nylon strain relief connector designed to protect wire and cable where they exit an enclosure, conduit fitting, or junction box. It grips the cable jacket firmly to prevent pulling, chafing, and abrasion at the entry point. The nylon construction resists moisture, mild chemicals, and corrosion, making it well suited for environments where a metallic fitting would be at risk. Electricians and panel builders use this type of fitting to maintain mechanical protection and comply with code requirements for cable securement at knockouts and enclosure entries.

The NSR12L fits a standard 1/2 inch knockout and is appropriate for residential and light commercial wiring applications. It is commonly installed on control panels, junction boxes, and enclosures where flexible cord, low-voltage cable, or jacketed wire needs to be anchored. The fitting is sold individually, making it easy to order the exact quantity needed for a job.

Installation Notes

Installation is performed by a qualified electrician in accordance with applicable NEC requirements for cable securement and protection at enclosure entries. De-energize the panel or enclosure completely before installing or replacing any fittings. Insert the connector body through the knockout from the outside, then secure the locknut from the inside and tighten by hand before final snugging with pliers. Do not overtighten the strain relief clamp screw, as nylon fittings can crack under excessive torque.
