Proto J4958CF Open End Crowfoot Wrench 1-13/16 in

Product Description

The PROTO J4958CF is an open end crowfoot wrench sized for 1-13/16 inch fasteners, designed for use with standard 3/8-inch or compatible drive ratchets and extensions. The crowfoot profile allows techs to reach nuts and fittings in confined spaces where a standard box or open end wrench cannot fit. The head measures 2.9 inches in diameter with a 0.38 inch head thickness, keeping the profile low in tight access points. A chrome-plated finish resists corrosion and makes cleanup easier after service work. This wrench is suited for plumbing, HVAC, and mechanical trades where access to deep-set or obstructed fasteners is a routine challenge.

This crowfoot wrench is used in residential and commercial service work where standard wrench access is blocked by adjacent components, housings, or structural members. Common applications include tightening or loosening fuel line fittings, refrigerant line connections, hydraulic fittings, and large hex fasteners found in mechanical equipment. The 1-13/16 inch size fits fastener sizes common in heavier mechanical assemblies and larger plumbing or HVAC connections. It is sold as a single piece and works with any compatible square drive ratchet or torque wrench.

Installation Notes

This tool is installed by HVAC technicians, plumbers, and mechanical service professionals. Ensure the fastener and crowfoot are fully engaged before applying torque to prevent rounding. When using with a torque wrench, account for any offset angle between the crowfoot and drive to apply the correct torque value per job specifications. Keep the wrench clean and inspect the chrome finish periodically for wear or corrosion.
