The PROTO J3080 is a double-end open end wrench sized at 1-7/8 inches by 2 inches, built for heavy-duty fastener work in trade and industrial environments. Constructed from steel with a satin finish, it features a 15-degree head angle that improves access in confined spaces and reduces fastener rounding. The J3080 meets ASME B107.6 and federal specification GGG-W-636E standards and carries a lifetime warranty. This wrench is intended for use by mechanics, millwrights, pipefitters, and other trade professionals who require a reliable, standard-format hand tool for large-diameter fasteners.
The J3080 is suited for maintenance, repair, and overhaul work across industrial, commercial, and heavy mechanical applications. Its dual-end design allows two different drive sizes to be accessed from a single tool, reducing the number of wrenches needed on the job. The 15-degree offset head angle is a standard configuration that helps clear obstructions when working on bolted flanges, large fittings, and structural connections.
Designed as a standard double-end open end wrench for use with large-diameter fasteners requiring 1-7/8 inch or 2 inch jaw openings across industrial, mechanical, and trade applications.
This wrench is a hand tool requiring no installation. Before use on pressurized systems, isolate and depressurize all lines per applicable job-site safety procedures. Inspect the jaw openings for wear or deformation before applying torque to critical fasteners. Use of cheater bars or extensions is not recommended and may void the warranty.
