Proto J1240-T500 Combination Wrench 1-1/4 Inches

Product Description

The PROTO J1240-T500 is a 12-point combination wrench built for professional trade use in mechanical, HVAC, plumbing, and industrial service applications. It features a 1-1/4 inch head size with a 15-degree offset angle, allowing technicians to work in confined spaces where a flat wrench cannot gain clearance. The overall length is 16-7/8 inches, providing ample leverage for high-torque fasteners. Constructed from steel with a chrome finish, the J1240-T500 meets ASME B107.100-2010 standards and carries a lifetime warranty. The tether-capable design supports use in elevated or safety-critical work environments.

This wrench is suited for residential and commercial service work where large fasteners are common, including equipment mounting, pipe flanges, structural connections, and mechanical room installations. The straight handle and 15-degree offset head make it practical for both open-side and box-end engagement in tight equipment cabinets or overhead installations. It is a standard hand tool for licensed HVAC technicians, plumbers, pipefitters, and general mechanical contractors who require a reliable, code-compliant wrench at the 1-1/4 inch size.

Installation Notes

This wrench is a hand tool requiring no installation. Technicians should confirm fastener size before applying torque to avoid rounding. When used in elevated or overhead applications, attach the tether point to an approved lanyard system per applicable fall-protection and dropped-object prevention protocols. Inspect the chrome finish regularly for chips or corrosion that could indicate compromised tool integrity.
