Proto J1242B Combination Wrench 1-5/16 in 15 Deg Offset

Product Description

The PROTO J1242B is a 1-5/16 inch combination wrench built for professional tradespeople who need a reliable, heavy-duty hand tool in tight or awkward fastener situations. The wrench features a 15-degree offset head angle on both the open and box ends, allowing clearance over obstructions when turning fasteners in confined spaces. Constructed from corrosion-resistant steel with a 12-point box end, the J1242B measures 17-5/8 inches overall and weighs 2.11 pounds. It meets ASME B107.100-2010 standards and is tether capable for use in elevated or safety-critical work environments.

This wrench is suited for heavy mechanical, industrial, and trade applications where 1-5/16 inch fasteners are common. The straight handle and offset head make it practical for HVAC equipment assembly, plumbing rough-in, electrical panel work, and structural mechanical installations. The tether-capable design makes it appropriate for overhead work or any site where dropped-tool protocols are enforced. It is intended for use by licensed tradespeople and experienced mechanical professionals.

Installation Notes

Always power down or de-energize equipment before using hand tools on mechanical connections associated with electrical or pressurized systems. Ensure the wrench is fully seated on the fastener before applying torque to prevent rounding. When used in elevated work environments, attach the tether point to an approved lanyard or tool-tethering anchor per site safety requirements. Inspect the wrench for cracks or deformation before each use and remove from service if damaged.
