The PROTO J112832L is a double-end box end wrench built for professional tradespeople who need reliable torque in tight spaces. Sized at 7/8 inch on one end and 1 inch on the other, this wrench features a 12-point box configuration on both ends, allowing engagement from more angles in confined work areas. The tool is manufactured from steel with a polished finish, meeting ASME B107.10 standards. It measures 17.09 inches in length and weighs 1.44 pounds, giving it the heft and reach needed for heavy-duty fastener work in HVAC, plumbing, and mechanical service applications.
This wrench is suited for residential and commercial service work where box end tools are required for hex-head fasteners on equipment, piping flanges, mechanical assemblies, and structural components. The dual-size design eliminates the need to carry two separate wrenches when working on fastener pairs of common imperial sizes. HVAC technicians, plumbers, pipefitters, and general mechanical contractors will find this tool applicable across a wide range of install and service scenarios.
Designed as a standard double-end box end wrench for use with 7/8 inch and 1 inch hex-head fasteners in trade and industrial service applications.
This wrench is a hand tool intended for use by licensed tradespeople and qualified mechanical technicians. Always de-energize and lock out equipment before performing any fastener work on energized systems. Use the correct end size to ensure full box engagement with the fastener to prevent rounding. Inspect the tool for cracks or deformation before each use and do not use as a striking tool or extend the handle with a cheater bar.
