The WILLIAMS COMFORT PRODUCTS 3728-TH is a double offset angle wrench sized for 7/8-inch fasteners. The double offset design positions the drive head at an angle to the handle, allowing access to recessed or obstructed fasteners that a standard wrench cannot reach. This wrench is a hand tool intended for use during installation, service, and maintenance tasks where clearance is limited. Trade professionals in HVAC, plumbing, and related mechanical trades reach for this style of wrench when working in tight cabinet spaces or around adjacent components.
The 3728-TH is suited for residential and light commercial service work where a 7/8-inch fastener size is common. Its offset geometry makes it practical for torquing fittings, nuts, and bolts in confined areas without requiring a straight-line approach. It is sold individually and is appropriate for any technician who needs reliable fastener access in restricted spaces.
Designed for general use with 7/8-inch fasteners encountered in HVAC, plumbing, and mechanical service applications.
This wrench is a hand tool used by HVAC technicians and plumbers during equipment installation and service. Always shut off power and close any relevant shutoff valves before working on equipment requiring this tool. Use the wrench within its rated jaw size to avoid rounding fasteners. Follow applicable local codes and manufacturer torque guidance when tightening fittings or mechanical connections.
