The WILLIAMS COMFORT PRODUCTS 3720-TH is a double open-end angle wrench sized for 5/8 inch fasteners. This hand tool is designed for service work in tight or awkward spaces where a standard wrench cannot reach or turn freely. The angled head geometry gives the technician additional clearance and leverage when working around equipment housings, valve bodies, or mounting hardware. At 0.25 pounds, it is a lightweight addition to a service bag without sacrificing durability. HVAC technicians, plumbers, and general mechanical tradespeople will find this wrench useful during installation and maintenance tasks.
This wrench is suited for residential and light commercial service applications where 5/8 inch fasteners are common. Typical uses include tightening or loosening flare fittings, valve packing nuts, union connections, and equipment mounting hardware. The double open-end design allows two different engagement angles on the same fastener, improving access in confined equipment compartments.
Designed for use with 5/8 inch fasteners and fittings encountered in standard HVAC, plumbing, and mechanical service work.
This wrench is a hand tool requiring no special installation. Before servicing any system component, shut off power, close relevant isolation valves, and relieve pressure where applicable. Use the appropriate torque for the fitting or fastener type being worked on per the equipment manufacturer specifications or applicable code. Do not use extension bars or cheater pipes on this wrench, as overloading a hand tool can cause slippage or damage to fittings.
