Proto J3055B Double End Open End Wrench 1-1/4 X 1-5/16 in

Product Description

The PROTO J3055B is a double-end open end wrench designed for heavy-duty fastener work in trade and industrial environments. Built from steel with a black finish, it features a 15-degree head angle that improves access in tight or obstructed spaces. The wrench spans two sizes — 1-1/4 inches and 1-5/16 inches — giving technicians two working ends in a single tool. It weighs 1.9 pounds and is backed by a lifetime warranty. HVAC techs, plumbers, pipefitters, electricians, and general maintenance crews rely on open end wrenches like this for nuts and fittings where a box end or socket cannot seat properly.

The J3055B is suited for residential and commercial maintenance applications, equipment rooms, mechanical systems, and field service work. The dual-size configuration is especially practical when working around pipe connections, flanged fittings, union nuts, and similar fasteners common in HVAC, plumbing, and industrial piping systems. The 15-degree offset head helps clear obstructions that would block a straight wrench from turning fully.

Installation Notes

Open end wrenches are a hand tool used by HVAC technicians, plumbers, pipefitters, and electricians across a wide range of service tasks. No power-down requirement applies to the tool itself, but always de-energize, depressurize, or isolate any system before working on fasteners connected to live circuits, pressurized lines, or gas piping. Apply force in the direction the open jaw can best bear load to avoid rounding fasteners.
