The WILLIAMS COMFORT PRODUCTS 10773 is a 3/8 inch drive crowfoot wrench sized at 23MM, designed for reaching fasteners in tight or obstructed spaces where a standard open-end or box wrench cannot fit. Crowfoot wrenches attach directly to a standard 3/8 inch drive ratchet or torque wrench extension, giving technicians the ability to apply controlled torque in confined areas. Weighing 0.27 pounds, this wrench is a compact, single-unit tool suited for HVAC, plumbing, and general mechanical service work where access is a consistent challenge.
The 10773 is well suited for residential and light commercial service applications. HVAC technicians, plumbers, and mechanical contractors will find it useful when working around line sets, manifolds, valve assemblies, and other hardware where clearance is limited. It is sold individually and is a direct addition to any 3/8 inch drive socket set already in the field.
Designed as a standard 3/8 inch drive crowfoot wrench compatible with any 3/8 inch drive ratchet, extension bar, or torque wrench used in HVAC, plumbing, and general mechanical service.
Installation and use of this tool applies to licensed HVAC technicians, plumbers, and mechanical service professionals. Always ensure the drive connection is fully seated on the ratchet or extension before applying torque. De-energize and depressurize the system at the service point before using any wrench on pressurized or energized components. Follow all applicable codes and manufacturer torque specifications for the fastener being serviced.
