Proto JSCV34 Combination Wrench 1-1/16 Inch Ratcheting

Product Description

The PROTO JSCV34 is a 1-1/16 inch combination wrench built for professional trade use in mechanical, HVAC, and industrial service applications. It features a 12-point ratcheting head with a reversing mechanism, allowing the technician to work in tight spaces without repositioning the wrench on the fastener. The head offset angle is 15 degrees, providing clearance over fastener heads and surrounding hardware. The overall length is 14-1/8 inches. Constructed from steel with a corrosion-resistant chrome finish, it meets ASME B107.100-2010 standards and is rated for tether attachment, making it suitable for elevated or safety-critical work environments.

This wrench is designed for use in commercial and industrial maintenance, mechanical contracting, and trade service work where a reliable combination wrench is required. The ratcheting function with reversing capability makes it well suited for confined areas common in HVAC equipment rooms, mechanical chases, and plumbing rough-in work. The tether-capable design supports tool-tethering programs used on elevated platforms, rooftops, and other drop-hazard work sites. It ships as a single unit with no minimum order beyond one piece.

Installation Notes

This wrench is installed and used by licensed mechanical, HVAC, and plumbing technicians as part of standard hand-tool service kits. Before use in energized or pressurized environments, follow applicable lockout/tagout procedures and depressurize or de-energize equipment as required by site safety protocols. When using in tethered-tool applications, attach an approved lanyard to the tether point before working at elevation. Do not apply cheater bars or extensions to the handle, as this can exceed the rated torque range of the tool.
