Proto J5376CF Open End Crowfoot Wrench 2-3/8 in

Product Description

The PROTO J5376CF is an open end crowfoot wrench designed for professional tradespeople working in confined spaces where standard wrenches cannot reach. Built to a 2-3/8 inch wrench size with a 4-3/8 inch head diameter and a 1/2 inch head thickness, this crowfoot attaches to a standard 1/2 inch drive torque wrench or extension. The chrome-plated finish provides corrosion resistance and makes it easy to wipe clean in the field. It is commonly used by mechanics, pipefitters, and maintenance technicians who need precise torque application on fasteners in restricted access areas.

This crowfoot wrench suits residential and commercial maintenance applications where a conventional box or open end wrench lacks the clearance to seat properly. Typical uses include fastener work on hydraulic lines, HVAC equipment, plumbing fittings, and structural assemblies where a drive extension must be used in place of a standard handle. The 2-3/8 inch wrench size targets larger fasteners common in industrial and heavy mechanical service work.

Installation Notes

This tool is installed by licensed mechanics, pipefitters, or maintenance technicians using a compatible 1/2 inch drive ratchet or torque wrench. Ensure the crowfoot is fully seated on the drive before applying torque to prevent rounding the fastener or damaging the tool. Follow all applicable torque specifications provided by the equipment manufacturer. De-energize and isolate all systems before working on any fasteners under load or pressure.
