Proto J3134 Open End Wrench Double End 1-1/16 in

Product Description

The PROTO J3134 is a double-ended open end wrench sized at 1-1/16 inches, built for professional trade use in mechanical, HVAC, and plumbing service applications. Constructed from steel with a chrome-plated finish, this wrench delivers corrosion resistance and a clean grip surface. The double-end head configuration features 15-degree and 60-degree head angles, giving technicians access to fasteners in confined or angled spaces where a standard straight wrench cannot seat properly. It carries a lifetime warranty, reflecting its intended use as a long-term hand tool in daily service environments.

This wrench is suited for residential and commercial maintenance work, mechanical service bays, and field service kits. The 1-1/16-inch size fits common fastener standards found in HVAC equipment, piping flanges, and general mechanical assemblies. The dual head angle design makes it particularly useful where bolt access is restricted by adjacent components or tight framing. It meets GGG-W-636E federal specifications for hand wrenches.

Installation Notes

This wrench is installed and used by licensed HVAC technicians, plumbers, pipefitters, and general mechanical service professionals. Always de-energize or shut off the relevant system before using hand tools on live mechanical assemblies. Ensure the wrench jaw is fully seated on the fastener flats before applying torque to prevent rounding. Inspect the chrome finish regularly for chips or corrosion that could affect grip or jaw integrity.
