Proto J4952CF Open End Crowfoot Wrench 1-5/8 Inch

Product Description

The PROTO J4952CF is a 1-5/8 inch open end crowfoot wrench designed for accessing fasteners in tight or recessed spaces where standard wrenches cannot reach. The crowfoot head attaches to a standard drive extension or torque wrench, giving technicians the leverage and precision needed for hard-to-reach nuts and bolts. The head measures 2.72 inches in diameter and 0.38 inches in thickness, keeping the profile low for confined-space work. A chrome-plated finish resists corrosion and makes cleanup easier after use. This wrench is built for use by mechanics, HVAC technicians, plumbers, and other trade professionals who require reliable hand tools in their daily service work.

The J4952CF is suited for a wide range of service and maintenance applications, including mechanical assemblies, pipefitting connections, and equipment installations where a standard open end or box wrench cannot be positioned. Its low-profile head is especially useful when working around obstructions such as tubing, fittings, or structural members. The inch-measurement sizing at 1-5/8 inch makes it appropriate for standard SAE fastener applications across residential and commercial trade work.

Installation Notes

A licensed mechanic or qualified trade professional should verify the correct drive size of the extension or torque wrench before attaching the crowfoot head. Ensure the drive connection is fully seated and secure before applying torque to avoid slippage or fastener damage. Do not use impact drivers with crowfoot wrenches unless the wrench is specifically rated for impact use.
