Williams Comfort Products JHW3758 Open End Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW3758 is a double-end open end wrench with a 1 13/16 inch opening and an overall length of 17 3/4 inches. Both wrench ends are the same size, allowing the tool to be used in four distinct positions by flipping or rotating the handle. The wrench heads are offset at 15 degrees and 60 degrees to the handle, giving technicians better access in confined spaces. A satin-chrome finish resists corrosion and wipes clean between uses. Meets ANSI B107.39 Type 2-Class 3 specifications. This is a hand tool suited for mechanical, HVAC, plumbing, and general trade applications.

The JHW3758 is built for trade professionals who need a reliable open end wrench with versatile positioning in tight installations. The thin head profile allows placement on fasteners where standard-thickness wrenches cannot reach. The 45-degree chamfer on the wrench ends seats the tool onto fasteners quickly, reducing slip risk during torque application. Its continuous arc jaw design limits jaw spread under load, making it more durable than traditional open-offset-V (OVO) profile designs. Suitable for use in HVAC equipment rooms, mechanical rooms, and field service where large fasteners and limited clearance are common.

Installation Notes

This wrench is a hand tool requiring no installation. Before use on any mechanical system, de-energize electrical components and shut off fluid or gas supply as required by applicable codes. Always confirm the wrench opening is fully seated on the fastener before applying torque to prevent rounding of fastener heads. Inspect the wrench for cracks or jaw spread before each use and remove from service if damage is found.
