Proto J5380CF Open End Crowfoot Wrench 2-1/2 Inch

Product Description

The PROTO J5380CF is a 2-1/2 inch open end crowfoot wrench designed for use with 1/2 inch drive torque wrenches and ratchet extensions. The head measures 4-3/8 inches in diameter and 1/2 inch in thickness, with a chrome-plated finish that resists corrosion and simplifies cleaning. This crowfoot is suited for fasteners in tight or recessed locations where a standard open-end wrench cannot reach. Mechanics, millwrights, and industrial maintenance technicians reach for crowfoot sets when working around obstructions on hydraulic fittings, fuel lines, and heavy equipment fasteners.

This wrench is appropriate for both commercial and industrial maintenance applications where access is restricted. The 2-1/2 inch jaw size accommodates large fasteners common in heavy equipment, truck drivetrain service, and industrial machinery. It is used as part of a crowfoot set or individually paired with a 1/2 inch drive extension for controlled torque application.

Compatibility

Installation Notes

Installation is performed by licensed mechanics or industrial maintenance technicians. Ensure the drive tool and crowfoot are fully seated before applying torque. When using a crowfoot at an angle offset from the drive tool, consult the applicable torque correction formula to maintain accurate fastener loading. Remove all load from the fastener and confirm the work area is safe before beginning disassembly.
