Proto J1072M Offset Box End Wrench 12 Point Double End

Product Description

The PROTO J1072M is a double-end offset box end wrench built for professional trade use in mechanical, HVAC, plumbing, and industrial service applications. It features a 12-point box end geometry on both ends, allowing engagement with standard hex fasteners at multiple approach angles. The offset handle design provides knuckle clearance in recessed or tight-access fastening locations. Constructed from steel with a polished finish, this wrench is suited for technicians who need a reliable non-ratcheting box end tool for torque-critical or confined-space work.

This wrench is intended for use by licensed HVAC technicians, plumbers, pipefitters, electricians, and general mechanical contractors working on equipment installations, service calls, and maintenance tasks. The double-end configuration means two fastener sizes are covered in a single tool, reducing the number of hand tools needed on a job. The offset angle aids access to fasteners that a straight wrench cannot reach cleanly.

Installation Notes

This wrench is used by trade professionals for fastener removal and installation during equipment service and maintenance. Always confirm the correct wrench size matches the fastener before applying torque to avoid rounding. Ensure equipment is de-energized and any pressurized systems are isolated before beginning work on fastened assemblies. Follow applicable codes and manufacturer service procedures for the equipment being serviced.
