Proto J1227M-T500 Combination Wrench 27 Mm Tether

Product Description

The PROTO J1227M-T500 is a 27 mm combination wrench built for professional tradespeople who need a reliable, standard-drive hand tool for fastener work in tight or elevated environments. It features a 12-point box end with a 15-degree offset angle, allowing better knuckle clearance in confined spaces. The wrench measures 14-7/8 inches overall and weighs 1.35 pounds. Constructed from steel with a polished finish, it is corrosion-resistant and tether capable, making it suitable for work at height or in controlled tool environments. It meets ASME B107.100-2010 standards and carries a lifetime warranty.

This wrench is suited for industrial maintenance, mechanical assembly, plumbing rough-in, HVAC equipment service, and electrical utility work where fastener sizes in the metric range are standard. The tether-capable design makes it appropriate for elevated work platforms, scaffolding, and any application subject to dropped-tool safety requirements. The straight handle and 15-degree offset provide comfortable torque application without repositioning on most hex fastener applications.

Installation Notes

This wrench is a hand tool intended for use by qualified tradespeople including HVAC technicians, plumbers, electricians, and industrial mechanics. Always de-energize, depressurize, or lock out equipment before applying torque to fasteners on live systems. When used in elevated or dropped-tool-sensitive environments, attach a rated tether through the tether point before use. Do not use extension bars or cheat pipes to increase leverage beyond what the tool is rated for.
