The PROTO JSCV40T is a ratcheting combination wrench designed for professional use in tight-clearance fastening applications. It features a 12-point box end with a 15-degree offset head and a straight handle, giving technicians the ability to drive fasteners in confined spaces without repositioning the tool after every swing. The wrench measures 16-3/4 inches overall and weighs 2.388 pounds. Constructed from steel with a corrosion-resistant chrome finish, it meets ASME B107.100-2010 standards and is rated tether capable, making it compatible with tool-tethering programs in elevated or safety-critical work environments.
The JSCV40T is suited for industrial, commercial, and heavy-trade applications where a reliable ratcheting combination wrench is required. The 1-1/4 inches head size addresses fasteners common in HVAC equipment frames, large plumbing fittings, electrical gear mounting hardware, and structural mechanical work. Licensed trades professionals and industrial maintenance techs will find the ratcheting and reversing function especially useful when working in areas with limited swing arc.
Designed for use with 1-1/4 inches fasteners across industrial, commercial, and mechanical trade applications.
This wrench is intended for use by qualified trades professionals working on mechanical, electrical, or plumbing systems. Always de-energize or depressurize the system before beginning fastener work on live equipment. Confirm the correct head size engagement before applying torque to avoid fastener rounding. When used in elevated or confined environments, attach the tether point to an approved lanyard in accordance with applicable site safety protocols.
