Ecm Industries Llc LNW-3PC Locknut Wrench Kit 3 Piece

Product Description

The ECM INDUSTRIES LLC LNW-3PC is a three-piece locknut wrench kit designed specifically for tightening and loosening locknuts in electrical and plumbing installations. The kit includes three wrenches sized for 1/2-inch, 3/4-inch, and 1-inch locknuts — the most common sizes encountered when securing conduit connectors, fittings, and bushings. Each wrench features a thin profile that fits into confined spaces where standard tools cannot reach. A specialty hooked tip latches onto the locknut to maximize turning leverage. Direction arrows are clearly etched into both ends of each wrench, eliminating guesswork during installation or removal.

This kit is suited for electricians, plumbers, and HVAC technicians working on conduit installations, panel rough-ins, service entries, and plumbing rough-in work where locknuts must be seated or removed in tight enclosures, junction boxes, or panel knockouts. The three included sizes cover the most frequently used trade locknut dimensions, making this kit a practical addition to a service bag or truck stock. Steel construction holds up to repeated daily use in commercial and residential settings.

Installation Notes

This tool is typically used by licensed electricians and plumbers during conduit installation, panel work, or pipe fitting. Power down circuits and de-energize panels before working near electrical enclosures. Ensure the hooked tip is fully seated on the locknut before applying rotational force to avoid slipping. Follow applicable NEC or IPC guidelines for locknut torque and fitting engagement requirements.
