Proto J53000CF 22 Pc Crowfoot Wrench Set 1/2 in Drive

Product Description

The PROTO J53000CF is a 22-piece, 1/2 inch drive open end crowfoot wrench set covering a size range of 15/16 inch through 2-1/2 inches. Each crowfoot fits standard 1/2 inch drive ratchets and extension bars, allowing technicians to reach fasteners in confined spaces where a standard open end wrench cannot turn. The set ships on a clip rail for organized storage and quick size identification on the job. Chrome finish provides corrosion resistance for shop and field use. The set meets ASME B107.6 standards for wrench design and dimensional tolerances. Plumbers, HVAC technicians, and pipefitters rely on crowfoot sets when torquing fittings, unions, and flare nuts in tight installations.

This set is suited for residential and commercial mechanical work where large-diameter fasteners and fittings are common, including HVAC refrigerant line connections, gas line unions, water supply connections, and equipment flange hardware. The wide size range from 15/16 inch up to 2-1/2 inches covers most standard inch-series fittings encountered in trade work. The 22 individual crowfoots store on an included clip rail, keeping the set intact during transport and in service vans or tool carts.

Key Features

• 22-piece set spanning 15/16 inch to 2-1/2 inches in standard inch sizes
• 1/2 inch drive square opening works with any standard 1/2 inch drive ratchet, breaker bar, or torque wrench
• Open end crowfoot profile reaches flats on fittings, unions, and flare nuts in restricted spaces
• Chrome finish resists corrosion in shop and field environments
• Meets ASME B107.6 dimensional and performance standards
• Clip rail storage keeps all 22 pieces organized and accounted for

Compatibility

Designed for use with standard 1/2 inch drive ratchets, torque wrenches, and extension bars. Covers inch-series fastener sizes commonly found in HVAC, plumbing, and mechanical systems requiring open end crowfoot access.

Installation Notes

Crowfoot wrenches are installed by licensed HVAC technicians, plumbers, and pipefitters working on fittings in restricted-access areas. Always de-energize equipment and shut off fluid or gas supply before servicing connected fittings. When used with a torque wrench, account for any angular offset between the crowfoot and the drive centerline, as this affects the applied torque value. Inspect each crowfoot for wear or damage before use and do not use on rounded or damaged fasteners.
