Proto J5323MCF Open End Crowfoot Wrench Chrome Metric

Product Description

The PROTO J5323MCF is a metric open end crowfoot wrench with a chrome-plated finish, designed for use with torque wrenches and ratchet drive extensions in professional trade applications. The crowfoot profile allows access to fasteners in confined or obstructed spaces where a standard open-end wrench cannot seat. At 2.8 inches in overall length, it is a compact wrench suited for automotive, HVAC, plumbing, and mechanical service work. The chrome plating provides corrosion resistance and makes cleanup easier in shop environments. This wrench is intended for installation and service technicians working with metric fasteners in tight or recessed locations.

The J5323MCF is used in residential and commercial service settings wherever metric fasteners must be torqued or loosened in restricted access areas. Typical applications include mechanical and HVAC equipment service, hydraulic line fittings, and equipment assembly where inline drive tools are required. The open end crowfoot design allows the wrench to attach to a square drive extension or torque wrench, giving technicians accurate torque application on metric fittings that a socket cannot reach.

Installation Notes

This wrench is installed by mechanics, HVAC technicians, and plumbers as part of a drive-tool assembly. Ensure the square drive connection is fully seated on the extension or torque wrench before applying force. Do not use cheater bars or extension pipes on the drive tool, as this can exceed the rated capacity of the wrench. Follow applicable service codes and equipment manufacturer torque specifications for the fastener being serviced.
