Proto JSCV28 7/8 Inch Ratcheting Combination Wrench

Product Description

The PROTO JSCV28 is a 7/8-inch ratcheting combination wrench built for professional tradespeople who need reliable torque in tight spaces. It features a 12-point box end with a 15-degree offset head and a straight handle, giving the user controlled leverage in confined work areas. The wrench is reversible, meaning the ratcheting direction can be switched without removing the tool from the fastener. Constructed from steel with a corrosion-resistant chrome finish, it meets ASME B107.100-2010 standards and carries a lifetime warranty. Overall length is 11-7/16 inches, and the head thickness is 1/4 inch. It is tether capable, making it appropriate for work-at-height applications where dropped tools are a safety concern.

This wrench is suited for mechanical, HVAC, plumbing, and electrical trade work where 7/8-inch fasteners are common. The ratcheting box end speeds up repetitive fastening tasks without breaking contact with the nut or bolt head. The 15-degree head offset lets the tool clear obstructions that block a standard flat wrench. It is appropriate for both residential and light commercial service work and fits comfortably in a standard tool roll or service bag. The tether-capable design meets requirements on job sites with fall-protection tool policies.

Installation Notes

Use this wrench only with properly sized 7/8-inch fasteners to avoid rounding. When working on energized or pressurized systems, follow all applicable lockout/tagout procedures before applying torque to any fitting or fastener. For work-at-height use, attach an appropriate tether lanyard to the tether point before beginning work. Inspect the ratcheting mechanism periodically and replace the tool if the pawl slips or the mechanism fails to engage cleanly.
