Proto J4944CF Open End Crowfoot Wrench 1-3/8 in

Product Description

The PROTO J4944CF is a 1-3/8 inch open end crowfoot wrench designed for use with standard drive ratchets and extensions. It delivers the reach and access of an open end wrench in a crowfoot profile, allowing technicians to torque fasteners in tight or recessed locations where a conventional wrench cannot fit. The head measures 2.4 inches in diameter and 0.38 inches thick, keeping the profile slim for confined spaces. A chrome-plated finish provides corrosion resistance and a clean surface for wiping down between uses. Weight is 0.29 pounds.

This crowfoot wrench is suited for automotive, HVAC, plumbing, and industrial maintenance work where hex or square fasteners must be reached from an angle or in a recessed bay. It is a practical addition to any service kit where straight or flex-head wrenches cannot seat properly. The 1-3/8 inch size covers common fastener sizes found on fittings, couplings, and mechanical assemblies in commercial and residential service environments.
