Proto J1228SPL Combination Wrench 7/8 Inch 15 Degree Offset

Product Description

The PROTO J1228SPL is a 7/8 inch combination wrench built for professional trade use in mechanical, HVAC, plumbing, and electrical service work. It features a 12-point box end with a 15-degree offset head angle that provides knuckle clearance in tight or recessed fastener locations. The wrench measures 12-17/32 inches overall and is manufactured from steel with a corrosion-resistant chrome finish. The straight handle is tether capable, making it suitable for use in elevated work environments or applications requiring tool retention compliance. This wrench meets ASME B107.100 standards and carries a lifetime warranty.

This combination wrench is suited for residential and commercial service applications where a 7/8 inch fastener size is common, including HVAC equipment installation, refrigeration piping connections, plumbing fixture work, and general mechanical assembly. The 15-degree offset box end allows access to fasteners that are recessed or obstructed by adjacent components without requiring a ratchet or extension. The open end provides quick engagement on exposed fasteners. Technicians working in confined equipment spaces will find the offset geometry practical for routine service tasks.

Installation Notes

This wrench is installed and used by licensed mechanical, HVAC, plumbing, and electrical tradespeople. Always de-energize equipment and shut off relevant fluid or gas supplies before performing fastener work on live systems. Do not use as a striking tool or extend the handle with a cheater bar, as this can damage the wrench and create a safety hazard. When used in elevated applications, secure the wrench to an approved tether anchor point before beginning work.
