Williams Comfort Products 10712 Crowfoot Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS 10712 is a 3/8 inch drive crowfoot wrench with a 1-1/8 inch open-end jaw. Crowfoot wrenches are designed for fasteners in tight or recessed locations where a standard socket or box wrench cannot reach. This style attaches directly to a 3/8 inch drive ratchet, extension, or torque wrench, allowing the technician to apply controlled torque to hex fasteners in confined spaces. It is sold individually and is a standard hand tool used across HVAC, plumbing, and mechanical trade applications.

Crowfoot wrenches of this drive and opening size are commonly used during equipment installation and service where line fittings, flare nuts, and hex-head fasteners are positioned in areas with limited clearance. Trade professionals including HVAC technicians and plumbers reach for this tool when working on refrigerant line connections, water supply fittings, and mechanical assemblies where conventional wrenches cannot seat properly.

Key Features

• 3/8 inch drive attachment compatible with standard ratchets, extensions, and torque wrenches
• 1-1/8 inch open-end jaw for hex fasteners and fittings of that size
• Compact crowfoot profile accesses recessed and tight-clearance fastener locations
• Sold as a single piece — no set required

Compatibility

Designed for use with any standard 3/8 inch drive ratchet handle, extension bar, or torque wrench.

Installation Notes

Crowfoot wrenches are installed and serviced by licensed HVAC technicians, plumbers, and mechanical contractors as part of routine tooling. When using a crowfoot on a torque wrench, account for the offset angle to ensure accurate torque application. Always ensure the jaw is fully seated on the fastener before applying force to avoid rounding. Power down equipment and depressurize or isolate systems before breaking any fittings.
