The WILLIAMS COMFORT PRODUCTS 3744-TH is a double angle wrench sized at 1.375 inches, designed for use in heating appliance service and installation. This wrench provides the angled geometry needed to reach fasteners in tight or offset positions where a standard wrench cannot make full contact. It is a hand tool intended for use by HVAC technicians and heating equipment service professionals working on gas-fired heating units and related components.
This wrench is suited for residential and light commercial heating service applications. The double angle design allows access to recessed or awkwardly positioned fittings and fasteners commonly encountered during heater installation or maintenance. Its compact form factor and 1.375-inch sizing make it appropriate for the fastener sizes found on Williams comfort heating products and similar equipment.
Designed as an OEM-style service wrench for use with Williams Comfort Products heating equipment requiring 1.375-inch fastener access.
This wrench is used by qualified HVAC or heating equipment technicians during installation or service of gas-fired heaters. Always shut off gas supply and disconnect power to the unit before beginning any service work. Use this tool only on fasteners within its rated size to avoid rounding or damage. Follow all applicable local codes and manufacturer service documentation when servicing heating equipment.
