Proto J5325MCF Open End Crowfoot Wrench Chrome Metric

Product Description

The PROTO J5325MCF is a metric open end crowfoot wrench finished in chrome plating. Crowfoot wrenches attach to a standard ratchet or torque wrench drive and allow access to fasteners in tight spaces where a conventional box or open end wrench cannot reach. The chrome finish resists corrosion and simplifies cleanup in field and shop environments. At 2.9 inches overall length and a package weight of 0.33 pounds, the J5325MCF is a compact, lightweight addition to any professional tool kit. Licensed mechanics, maintenance technicians, and HVAC service professionals commonly use crowfoot sets when working around compressors, manifolds, and other closely spaced fittings.

This crowfoot wrench is sized to the metric system of measurement and is suited for use in both residential and commercial service environments. It fits applications where a standard socket cannot engage a fastener due to obstructions or limited vertical clearance. Typical install scenarios include engine and equipment service, HVAC refrigerant line fittings, plumbing connections, and general mechanical maintenance where a ratchet drive must be offset from the fastener centerline.

Compatibility

Designed as an OEM-style replacement and standard-fitment crowfoot wrench compatible with any 3/8-inch or appropriate metric drive ratchet or torque wrench accepting crowfoot attachments. No specific model compatibility data was provided in the product input.

Installation Notes

Crowfoot wrenches are installed by trade mechanics, HVAC technicians, and plumbers as part of a ratchet or torque wrench drive setup. Always ensure the drive square is fully seated in the crowfoot before applying torque to prevent slippage or rounding of the fastener. Disengage any energy source or shut off system pressure before working on fittings or fasteners in live systems. Inspect the tool for cracks or wear before each use.
