Proto J5350CF Open End Crowfoot Wrench 1-9/16 in

Product Description

The PROTO J5350CF is an open end crowfoot wrench designed for use with 1/2-inch drive ratchets and extensions. It accepts a 1-9/16-inch fastener and delivers the reach and access needed in tight or obstructed spaces where a standard open-end wrench cannot seat properly. The chrome-plated finish resists corrosion and makes the tool easy to clean after use. With a head diameter of 3-3/32 inches and a head thickness of 1/2 inch, the wrench is sized for firm fastener engagement without adding excessive bulk. Mechanics, HVAC technicians, and plumbers commonly use crowfoot wrenches when servicing equipment with recessed or hard-to-reach fittings and fasteners.

This crowfoot wrench suits residential and commercial service work where standard sockets and wrenches are blocked by piping, valves, flanges, or structural framing. It is a practical addition to any service kit used on equipment with awkward bolt placement, including HVAC units, hydronic systems, and plumbing assemblies. The tool pairs with any standard 1/2-inch drive torque wrench, ratchet, or extension bar, making it versatile across a wide range of service calls.

Installation Notes

Install and remove fasteners only after confirming the system is de-energized, depressurized, or otherwise safe for service as required by applicable codes and site procedures. Seat the crowfoot wrench squarely on the fastener before applying torque to prevent rounding. When used with a torque wrench, account for any offset angle between the crowfoot and the drive axis if precise torque values are required per equipment specifications. This tool is intended for use by qualified trade professionals familiar with hand tool safety practices.
