Proto J3122 Double End Open End Wrench 11/16 in

Product Description

The PROTO J3122 is a double-ended open end wrench built for professional trade use in mechanical, HVAC, and plumbing service applications. Constructed from steel with a chrome-plated finish, this wrench features a 15-degree and 60-degree head angle on opposing ends, giving technicians two working positions in a single tool. The 11/16-inch jaw size handles a common fastener dimension found across HVAC equipment, pipe fittings, and mechanical assemblies. Backed by a lifetime warranty, the J3122 is designed to meet the demands of daily professional use.

This wrench is suited for residential and commercial service work where technicians need reliable access to hex fasteners in tight or angled spaces. The dual head angle configuration — 15 degrees on one end and 60 degrees on the other — allows the tech to reposition without swapping tools, reducing time on fasteners in confined equipment bays, panel enclosures, and piping runs. Plumbers, HVAC technicians, and pipefitters will find the 11/16-inch size appropriate for common service tasks.

Installation Notes

This wrench is used by HVAC technicians, plumbers, and pipefitters during equipment installation and service. Ensure the correct jaw size is confirmed before applying torque to avoid rounding fastener heads. When working on energized equipment or active piping systems, de-energize electrical circuits and isolate pressure before loosening or tightening fittings. Follow applicable codes and manufacturer torque guidance for the fastener being serviced.
