Williams Comfort Products JHW1731B Open End Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1731B is a double-opening open end wrench sized at 13/16 inch and 7/8 inch, built for fastener access in tight or standard service situations. The wrench features a continuous arc jaw design that resists spreading under load, making it more structurally rigid than older open-oval designs. A 45-degree chamfer on each wrench end allows the tool to seat quickly onto fasteners without fumbling. The satin-chrome finish reduces glare, provides a secure grip, and wipes clean between jobs. Weighing 0.58 pounds, this is a hand tool suited for licensed trades and experienced service professionals working in mechanical, HVAC, and plumbing applications.

The JHW1731B is a standard-length open end wrench intended for professional service work where two common fastener sizes are needed from a single tool. Its compact profile at approximately 9.8 inches in length and 0.3 inches in height suits it for use in moderately confined spaces. Typical applications include mechanical room equipment, gas valve connections, union fittings, and structural fasteners encountered in HVAC, plumbing, and general trade service. It is sold as an individual unit and meets ANSI B107.6 federal specifications.

Installation Notes

This wrench is a hand tool installed by licensed HVAC technicians, plumbers, pipefitters, and general mechanical trades. Always de-energize electrical equipment and shut off gas or fluid supply before using hand tools on service connections. Do not use extension bars or pipe extensions on open end wrenches, as this can exceed the tool's design load and cause jaw spreading or failure. Inspect the wrench jaws before each use and retire the tool if deformation or wear is present.
