Proto J4915MCF Open End Crowfoot Wrench 1-11/32 in

Product Description

The PROTO J4915MCF is an open end crowfoot wrench designed for use with standard 1/4 inch drive ratchets and extensions. It features a 1-11/32 inch head diameter and a 1/4 inch head thickness, making it suited for fasteners in confined spaces where a conventional open end wrench cannot reach. The overall length is 1-5/8 inches. The chrome-plated finish resists corrosion and makes it easy to wipe clean in the field. This tool meets ASME B107.21 and Federal Specification GGG-C-1507b standards. Mechanics, plumbers, HVAC technicians, and other trade professionals use crowfoot wrenches when clearance is limited around a fastener.

This crowfoot wrench is suited for use in tight-clearance service work across mechanical, plumbing, and HVAC applications. Typical uses include tightening or loosening fittings, line connectors, and fastener heads that are recessed or surrounded by adjacent components. The shallow 1/4 inch head thickness allows entry into spaces where a standard wrench or socket would not fit. The 1-11/32 inch opening accommodates the corresponding fastener or fitting size in those scenarios.

Installation Notes

Crowfoot wrenches are installed by attaching them to a matching drive ratchet or torque wrench before applying force to a fastener. Always confirm the drive size of your ratchet matches the wrench drive before use. Do not use extensions or adapters that could cause misalignment and slipping under load. Keep the wrench face fully seated on the fastener to avoid rounding.
