Williams Comfort Products 10720 Crowfoot Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS 10720 is a 3/8 inch drive crowfoot wrench with a 1-5/8 inch open end opening, designed for reaching fasteners in tight or obstructed spaces where a standard wrench or socket cannot fit. Crowfoot wrenches attach to a standard ratchet or torque wrench via a square drive and allow technicians to apply controlled torque to hex fasteners, nuts, and fittings without requiring direct inline access. Weighing 0.29 pounds, the 10720 is a compact, single-piece tool suited for professional use in HVAC, plumbing, and mechanical service applications.

This crowfoot wrench is used in trade service environments where access to fasteners is restricted by surrounding components, piping, or structural members. The 1-5/8 inch open end size is common in larger mechanical and plumbing fittings, making this tool relevant for HVAC system work, pipe fitting, and equipment service. It is sold individually and is compatible with any standard 3/8 inch drive ratchet, extension, or torque wrench.

Compatibility

Designed for use with standard 3/8 inch drive ratchets, torque wrenches, and extensions. Suitable for professional HVAC, plumbing, and mechanical service applications requiring a 1-5/8 inch open end crowfoot fit.

Installation Notes

Crowfoot wrenches are installed by licensed or experienced trade technicians during equipment service or installation. Always ensure the drive connection is fully seated on the ratchet or torque wrench before applying force to prevent slippage. When used on a torque wrench at an angle offset from inline, consult the torque wrench manufacturer guidelines for angle correction factors. Isolate and de-energize or shut off the relevant system before servicing any fasteners on live mechanical or HVAC equipment.
