Proto J1228H-T500 Combination Wrench 7/8 Inch Tether

Product Description

The PROTO J1228H-T500 is a 7/8-inch combination wrench built for trade professionals who need a reliable, durable hand tool for fastener work in demanding environments. The open end and 6-point box end are forged from steel with a chrome finish that resists corrosion. The box end sits at a 15-degree offset angle, giving knuckle clearance in tight spaces without sacrificing torque. At 12.5 inches overall length, the handle delivers solid leverage for standard 7/8-inch fasteners. The wrench is tether capable, making it suitable for work at height or in environments where dropped tools are a safety concern.

This wrench is used across HVAC, plumbing, electrical, and general mechanical trades wherever 7/8-inch hex fasteners appear. Common applications include equipment mounting hardware, pipe flange bolts, conduit fittings, and unit connections on commercial and residential systems. The straight handle and offset box end make it a practical choice for both overhead and bench work. It conforms to ASME B107.100 standards, which is required on many jobsites and service contracts.

Compatibility

Designed as an OEM-style replacement or direct-service combination wrench for use with 7/8-inch SAE hex fasteners in HVAC, plumbing, and mechanical trade applications.

Installation Notes

This wrench is a hand tool requiring no installation, but proper use guidelines apply. Before servicing any equipment, follow lockout/tagout procedures per OSHA standards and shut down all power, gas, or fluid supply to the system. When using at height or in elevated work areas, attach the tether point to an approved tool lanyard to comply with dropped-object prevention requirements. Do not use as a striking tool or extend with a cheater bar, as this can cause tool failure or fastener damage.
