Proto JSCR28T 7/8 Inch Ratcheting Combination Wrench

Product Description

The PROTO JSCR28T is a 7/8-inch ratcheting combination wrench built for professional tradespeople who need speed and control in tight fastener work. The open-end and box-end design gives two attack angles on the same tool, and the ratcheting box end eliminates the need to lift and reposition on every stroke. The wrench measures 11-7/16 inches overall and carries a 0-degree head offset with a 15-degree opening angle, making it well suited for flat work surfaces and confined fastener locations. Chrome finish provides corrosion resistance over the steel body, and the tether-capable design supports tool-drop prevention systems on elevated job sites.

This wrench fits into daily use for HVAC service techs, plumbers, pipefitters, electricians, and general mechanical contractors who work with 7/8-inch fasteners on equipment frames, flanged fittings, conduit straps, and structural connections. The 12-point box end engages rounded or worn fasteners more reliably than a 6-point in high-cycle service environments. The straight handle and 0-degree offset keep knuckles clear on flat panel and equipment-base applications. At 0.78 pounds, the wrench carries without fatigue during extended service calls.

Installation Notes

Inspect the wrench for cracks or deformation before each use and do not use a damaged tool. When using the ratcheting box end, confirm the ratchet direction is set correctly before applying torque to avoid fastener damage. On elevated work sites, attach the tether point to an approved lanyard system per site safety requirements before beginning work. Do not use extension bars or cheater pipes on this wrench handle.
