Proto J1244B Combination Wrench 1-3/8 in 15 Deg Offset

Product Description

The PROTO J1244B is a combination wrench built for professional tradespeople who need a reliable, full-size hand tool for heavy fastener work. It features a 1-3/8 inch head size with a 15-degree offset angle, allowing clearance over obstructions in tight fastener environments. The 12-point box end seats on fastener flats for solid engagement, while the open end provides quick repositioning. Overall length is 18-1/2 inches. Constructed from steel with a corrosion-resistant finish, the J1244B is rated for long-term service in demanding shop, field, and industrial settings. The wrench is tether capable, supporting use in elevated or drop-sensitive work zones.

This wrench fits into general mechanical, HVAC, plumbing, and industrial maintenance work where large-diameter fasteners are common. The 15-degree head offset makes it well-suited for confined spaces where a flat wrench cannot achieve adequate swing arc. It is appropriate for use by licensed mechanics, pipefitters, HVAC technicians, and maintenance trades working on equipment frames, flanges, and heavy-duty hardware. The straight handle and full-length design provide the leverage needed for high-torque applications on larger fasteners.

Installation Notes

Installation and service work requiring this wrench should be performed by qualified tradespeople following applicable codes and safety procedures. De-energize, depressurize, or lock out equipment before servicing fastened connections. Inspect the wrench for cracks or deformation before each use and do not use damaged tooling. When working at height, secure the wrench to an anchor point using a compatible tether to prevent dropped-tool hazards.
