The WILLIAMS COMFORT PRODUCTS JHW1038A is a double-opening open end wrench with a 1 3/8 inch and 1 7/16 inch opening, built for professional service work where fast, reliable fastener engagement matters. The continuous arc jaw design resists spreading under load and delivers greater structural strength compared to older OVO-style geometry. A 45-degree chamfer on each wrench end allows rapid placement on fastener flats even in tight or awkward access points. The satin-chrome finish reduces glare, resists corrosion, and wipes clean quickly during service calls. This wrench meets ANSI B107.6 specifications.
The JHW1038A suits residential and commercial service environments where larger fastener sizes are encountered on equipment housings, flanges, piping connections, and structural fittings. It is sold individually and is appropriate for HVAC technicians, plumbers, pipefitters, and general mechanical tradespeople who need a reliable, standard-reach open end wrench in the larger size range. The dual-opening format increases utility by covering two fastener sizes in a single tool.
Designed as a standard open end wrench for use with 1 3/8 inch and 1 7/16 inch fasteners across a wide range of mechanical, HVAC, plumbing, and pipefitting applications.
Used by licensed HVAC technicians, plumbers, and pipefitters in equipment service and installation work. Always de-energize and isolate the system — electrical, gas, or water — before applying hand tools to fasteners on live equipment. Confirm fastener size before applying the wrench to avoid rounding flats. Do not use extension bars or cheater pipes on standard open end wrenches, as this can cause jaw spreading or fastener damage.
