Proto J1290 Combination Wrench 2-13/16 Inch 34 Inch Oal

Product Description

The PROTO J1290 is a full-size combination wrench built for heavy-duty industrial and mechanical service work. It features a 2-13/16 inch head size with a 15-degree offset angle, a 12-point box end, and a straight handle with an overall length of 34 inches. Constructed from steel with a corrosion-resistant finish, this wrench is tether capable, making it suitable for use in elevated or overhead work environments where dropped-tool protocols are required. At 17.83 pounds, it is designed for high-torque applications where a standard-length wrench cannot generate sufficient leverage.

This wrench is intended for use by maintenance technicians, millwrights, pipefitters, and industrial mechanics working on large fasteners in commercial, industrial, and heavy equipment settings. The 34-inch overall length provides extended reach and torque multiplication for large-diameter fasteners common in mechanical rooms, process piping, structural assemblies, and heavy machinery. The 15-degree offset at the box end allows clearance in recessed or confined bolt patterns.

Key Features

• 2-13/16 inch head size for large industrial fasteners
• 15-degree offset angle on the box end for clearance in tight applications
• 12-point box end engages fasteners from multiple positions
• 34-inch overall length delivers extended reach and high torque leverage
• Tether capable design supports dropped-object prevention programs
• Corrosion-resistant steel construction for demanding service environments
• Meets ASME B107.100-2010 standard

Compatibility

Designed as a large-format combination wrench for industrial fastener applications requiring a 2-13/16 inch opening. Consult application requirements to confirm fitment with specific fastener standards.

Installation Notes

Ensure the fastener head is fully seated in the wrench opening before applying torque to prevent rounding. When used in elevated or overhead work, attach the tether point to an approved lanyard or tool retention system per site dropped-object prevention policy. Inspect the wrench for cracks, deformation, or corrosion before each use and remove from service if damage is found.
