Proto J5368CF Open End Crowfoot Wrench 2-1/8 Inch

Product Description

The PROTO J5368CF is an open end crowfoot wrench built for professional use in tight or obstructed fastener locations where a standard open-end or box wrench cannot reach. It accepts a 1/2-inch drive ratchet or extension, giving technicians full torque control without direct handle access. The wrench is sized at 2-1/8 inches and features a chrome-plated finish for corrosion resistance and easy cleaning. Head diameter measures 3-31/32 inches with a head thickness of 1/2 inch, keeping the profile low in confined spaces. HVAC techs, plumbers, mechanics, and general trades rely on crowfoot sets when working around obstructions on refrigerant line fittings, pipe unions, conduit locknuts, and similar fasteners.

This crowfoot wrench is suited for residential and commercial service work wherever standard wrench access is blocked. It fits into mechanical rooms, equipment bays, and inline piping runs where fasteners must be turned without swinging a full-length handle. The open-end design allows side access to the fastener, making it useful on flare nuts, union connections, and panel hardware. It is part of a 1/2-inch drive accessory setup and pairs with standard 1/2-inch drive ratchets, breaker bars, and torque wrenches in a technician's tool kit.

Installation Notes

Crowfoot wrenches are installed by licensed and journeyman-level tradespeople including HVAC technicians, plumbers, and pipefitters. Ensure the crowfoot is fully seated on the fastener before applying torque to prevent rounding. When using with a torque wrench, account for any angular offset to maintain accurate torque readings per the fastener specification. Inspect the chrome surface before use and retire the tool if cracks, chips, or deformation are present.
