Proto J1234BASD Combination Wrench 1-1/16 in 15 Deg Offset

Product Description

The PROTO J1234BASD is a 12-point combination wrench designed for heavy-duty fastener work in industrial, mechanical, and trade service environments. It features a 1-1/16 inch head size with a 15-degree offset angle, giving technicians the clearance needed to drive fasteners in tight or obstructed spaces. The straight handle measures 14-7/8 inches overall, providing leverage appropriate for large fasteners. Constructed from steel with a corrosion-resistant finish, this wrench is built for repeated use in demanding conditions. Electricians, HVAC technicians, plumbers, and maintenance professionals will find this tool suitable for structural, equipment, and piping fastener applications.

This combination wrench is suited for professional trade use where a reliable, full-size open-end and box-end tool is required. The 15-degree head offset reduces knuckle clearance issues on recessed or flush-mounted fasteners. The tether-capable design makes it appropriate for elevated work environments where tool retention and drop prevention are required by site safety protocols. It is appropriate for general mechanical service, equipment installation, and maintenance work across HVAC, plumbing, electrical, and industrial trades.

Installation Notes

This wrench is used by licensed and journeyman tradespeople across HVAC, plumbing, electrical, and general mechanical service. Before working on pressurized systems, de-energize electrical circuits and relieve system pressure per applicable codes including NEC, IFGC, and IPC as appropriate to the trade. Inspect the wrench for cracks or deformation before each use and do not use extension bars or cheater pipes on the handle, as this can exceed the tool design limits and cause fastener or tool failure.
