Proto J1228MASD-TT Combination Wrench 28 Mm Tether Capable

Product Description

The PROTO J1228MASD-TT is a 28 mm combination wrench built for professional trade use in mechanical, HVAC, plumbing, and industrial maintenance applications. It features a 15-degree offset head that provides knuckle clearance in tight spaces, allowing technicians to drive fasteners where a flat wrench cannot reach. The wrench is machined from steel with a satin finish that reduces glare and resists corrosion. At 15.5 inches overall length, it delivers the leverage needed for larger fasteners. A 12-point box end engages hex fasteners securely, and the tether-capable design supports use in elevated work environments where dropped tools are a safety hazard.

This wrench is suited for residential and commercial mechanical installations where 28 mm fasteners are common, including equipment mounting, pipe flange work, and structural hardware. The tether-capable handle makes it appropriate for rooftop HVAC work, elevated platforms, and any job site with overhead personnel or drop-zone restrictions. Licensed HVAC technicians, pipefitters, plumbers, and industrial maintenance professionals are the primary users of this tool.

Installation Notes

This wrench is a hand tool used by licensed HVAC technicians, pipefitters, and plumbers in both service and installation tasks. When working at elevation, attach the tether point to an approved tool lanyard rated for the wrench weight before use. Inspect the wrench for cracks or deformation before each use and remove from service if damage is found. Follow applicable site safety plans and OSHA requirements when working on elevated surfaces or near energized equipment.
