Proto J1185-A Offset Box End Wrench 3/4 X 7/8 in 12 Point

Product Description

The PROTO J1185-A is a double-end offset box end wrench designed for professional use in tight or recessed fastener locations. It features a 12-point box end on both a 3/4-inch and a 7/8-inch opening, making it suitable for a wide range of hex fastener sizes in a single tool. The offset geometry positions the head at an angle from the handle, providing knuckle clearance and improved access in confined spaces. Constructed from steel with a polished finish, the J1185-A is built for repeated use in demanding trade environments. Mechanics, HVAC technicians, plumbers, and electricians working on equipment fasteners will find this wrench a practical addition to their hand tool set.

This wrench is well suited for service and installation work on mechanical equipment, piping assemblies, electrical panels, and HVAC components where standard open-end or combination wrenches cannot reach flush or recessed fasteners. The double-end configuration provides two common fastener sizes in one compact tool, reducing the number of tools needed on a service call. The reversing feature allows use in either direction without repositioning.

Key Features

• Double-end design with 3/4-inch and 7/8-inch box openings for two fastener sizes in one tool
• 12-point box end geometry engages fasteners with more contact points, reducing the risk of rounding
• Offset head angle provides knuckle clearance and improved access in confined or recessed areas
• Steel construction with polished finish for durability and corrosion resistance
• Reversing capability allows use in both tightening and loosening directions

Compatibility

Designed as an OEM-style hand tool replacement or addition for professional tool sets requiring 3/4-inch and 7/8-inch double-end offset box end wrench coverage.

Installation Notes

This wrench is a hand tool used by licensed tradespeople across HVAC, plumbing, electrical, and mechanical service work. Always ensure fasteners are fully engaged with the box end before applying torque to avoid slippage. Inspect the wrench for cracks or deformation before each use and remove from service if damage is found. Follow all applicable safety guidelines for hand tool use as outlined by your trade authority or employer.
