Proto J3136 Open End Wrench 1-1/8 Inch Double End

Product Description

The PROTO J3136 is a double-ended open end wrench sized at 1-1/8 inches, built from chrome-plated steel for corrosion resistance and long service life. The wrench features a 15-degree and 60-degree head angle on opposing ends, giving technicians access to fasteners in tight or awkward spaces. It meets GGG-W-636E federal specifications, a standard commonly required in industrial, commercial, and government maintenance environments. At 0.75 pounds, it is a solid hand tool suited for mechanical, HVAC, plumbing, and general trade use wherever a 1-1/8-inch open end wrench is called for.

This wrench is appropriate for residential and commercial service work involving hex fasteners, fittings, and nuts in the 1-1/8-inch range. The dual-angle head design makes it practical for confined installation spaces where a straight pull is not possible. Plumbers, HVAC technicians, pipefitters, and general maintenance mechanics will find the offset head angles useful when working around obstructions on equipment, piping, or structural assemblies. The chrome finish resists corrosion during storage and repeated use in damp or outdoor service conditions.

Installation Notes

This wrench is a hand tool requiring no installation. Use the appropriate head angle end to gain clearance around obstructions before applying force to a fastener. Inspect the wrench for cracks or deformation before use and do not use pipe extensions or cheater bars on the handle, as this can damage the tool and create a safety hazard. Store in a dry environment to preserve the chrome finish.
