The VALUE COLLECTION BD-17355 is a steel, non-insulated conduit locknut designed to secure conduit fittings to electrical enclosures, junction boxes, and panels. The threaded connection type allows the locknut to thread onto the conduit fitting hub and tighten against the enclosure wall, creating a firm mechanical connection. At a 1-1/2 inch trade size, this locknut fits standard 1-1/2 inch threaded rigid metal conduit (RMC) and intermediate metal conduit (IMC) fittings. Electricians and electrical contractors install this hardware during rough-in and finish wiring work on commercial and residential electrical systems.
This locknut is suited for use in standard conduit installations where a non-insulated steel locknut is acceptable per local code. Typical applications include securing conduit connectors and couplings at electrical panel knockouts, junction box entries, and equipment enclosures. The 1-1/2 inch trade size is common in commercial electrical work, industrial control panels, and service entrance conduit runs. This item is sold in a pack of 5, making it practical for single-trade or multi-trade jobs requiring multiple termination points.
Designed as an OEM-style replacement and standard-use locknut for 1-1/2 inch trade size threaded conduit fittings used with rigid metal conduit and intermediate metal conduit systems.
Installation should be performed by a licensed electrician in accordance with NEC requirements for conduit terminations. De-energize all circuits and verify with a voltage tester before working inside any panel or enclosure. Thread the locknut onto the conduit fitting hub before insertion, then tighten firmly against the enclosure wall using a locknut wrench or screwdriver set in the locknut teeth. Inspect for full thread engagement to ensure a secure mechanical and bonding connection.
