Proto J1229M-T500 Combination Wrench 29 Mm Tether Capable

Product Description

The PROTO J1229M-T500 is a 29 mm combination wrench built for professional tradespeople who need a reliable, full-size open-end and box-end tool in a single piece. The box end features a 15-degree offset angle and a 12-point configuration, giving technicians better knuckle clearance and versatile access in tight fastener locations. The wrench measures 15.75 inches overall and weighs 1.48 pounds. Constructed from steel with a polished finish, it meets ASME B107.100 standards and carries a lifetime warranty. The straight handle design keeps the tool familiar and balanced during extended use.

This wrench is suited for heavy equipment maintenance, industrial facilities, utility work, and any trade application requiring a large-format metric wrench. The 29 mm head size fits fasteners common on heavy machinery, structural equipment, and large-diameter pipe fittings. The tether-capable design makes it appropriate for elevated work environments where tool retention is required by site safety protocols, including telecommunications towers, steel erection, and elevated mechanical platforms.

Installation Notes

This wrench is intended for use by qualified tradespeople including millwrights, pipefitters, electricians, and mechanical contractors. Always ensure fasteners are fully seated in the box end before applying torque to reduce fastener rounding. When using in tethered applications, inspect the tether attachment point and lanyard before each use in accordance with applicable site safety requirements. Do not use extension bars or cheater pipes on the handle, as this exceeds the design load of the tool.
