The WILLIAMS COMFORT PRODUCTS 3726-TH is a double offset angle wrench sized for 13/16 inch fasteners. The offset geometry positions the handle away from the work surface, providing clearance in tight or recessed installations where a standard wrench cannot achieve a full swing. This type of wrench is commonly used by HVAC technicians, plumbers, and gas service professionals when accessing fasteners in confined spaces within equipment cabinets, valve assemblies, and piping connections. It is sold individually and is suited for hand-tool service work across residential and light commercial applications.
The 3726-TH is appropriate for use in service scenarios where fastener access is restricted by surrounding components, panels, or piping. The 13/16 inch sizing fits common fastener sizes encountered in HVAC equipment, gas valve hardware, and plumbing fixture connections. Trade professionals who regularly work inside air handler cabinets, furnace compartments, or tight utility spaces will find the offset angle design practical for routine service and installation tasks.
Designed for general service use on 13/16 inch fasteners in HVAC, plumbing, and gas equipment installations and repairs.
This wrench is a hand tool intended for use by qualified trade professionals during equipment service and installation. Always de-energize electrical equipment and shut off gas or water supply before accessing fasteners on live systems. No power tools or torque equipment are required for use with this wrench. Follow applicable local codes and manufacturer service procedures when working on any mechanical system.
