Proto J4972CF Open End Crowfoot Wrench 2-1/4 Inch

Product Description

The PROTO J4972CF is an open end crowfoot wrench designed for use with 3/8-inch or 1/2-inch drive ratchets and extensions. It fits fasteners requiring a 2-1/4 inch wrench size and is built for confined spaces where a standard open-end wrench cannot be positioned. The head measures 0.53 inches in diameter and 0.25 inches thick, allowing access in tight clearance applications. The chrome-plated finish provides corrosion resistance and makes cleanup straightforward. This wrench is appropriate for mechanics, HVAC technicians, plumbers, and other trade professionals working in restricted access environments.

Crowfoot wrenches like the J4972CF are used wherever a drive ratchet or torque wrench is needed but a conventional wrench head cannot seat on the fastener due to surrounding structure or components. Common applications include fastening or loosening fittings on HVAC equipment, piping assemblies, and mechanical systems where standard box or open-end wrenches lack the clearance to turn. The 2-1/4 inch size addresses larger fasteners and fittings frequently encountered in commercial and industrial service work.

Installation Notes

Crowfoot wrenches are installed by a licensed mechanic or trade technician using a compatible square drive ratchet or torque wrench. Ensure the drive tang seats fully in the crowfoot socket before applying torque. When used on pressurized systems such as plumbing or HVAC refrigerant lines, shut off and relieve system pressure before loosening or tightening fittings. Do not use with damaged or worn drive tools that may slip under load.
