Proto J1221MASD Combination Wrench 21 Mm 15 Degree Offset

Product Description

The PROTO J1221MASD is a 21 mm combination wrench built for professional trade use in industrial, mechanical, and maintenance applications. It features a 15-degree offset head angle with a 12-point box end and an open end on the opposite side, allowing access to fasteners in tight or angled spaces. The wrench measures 11-13/16 inches overall length and is constructed from steel with a satin finish that resists corrosion and reduces glare. It is tether capable, making it suitable for work-at-height environments where dropped-tool control is required. This wrench meets ASME B107.100 standards and carries a limited lifetime warranty.

The J1221MASD is suited for mechanical contractors, industrial maintenance technicians, and trade professionals who work on equipment requiring metric fastener sizes. The tether-capable design makes it appropriate for elevated work platforms, overhead mechanical work, and confined-space maintenance tasks. The straight handle provides good torque leverage, and the satin finish makes the wrench easy to clean after use in shop or field conditions. It is packaged and sold individually.

Installation Notes

This wrench is intended for use by qualified mechanical and maintenance technicians. Before servicing any equipment, de-energize electrical systems and relieve stored mechanical or hydraulic pressure per applicable safety procedures. When using in elevated or overhead work areas, attach the wrench to an approved tether anchor point before use. Inspect the wrench for cracks or deformation before each use and do not use it as a striking tool or extend the handle with a cheater bar.
