The WILLIAMS COMFORT PRODUCTS 3734-TH is a double offset angle wrench sized at 1-1/16 inches. The double offset geometry positions the drive head at an angle relative to the handle, providing clearance in confined or obstructed workspaces where a standard wrench cannot reach. This wrench is a hand tool suited for mechanical, plumbing, HVAC, and general trade use wherever a 1-1/16-inch fastener or fitting requires turning in a tight access area. At 0.61 pounds, it is a lightweight tool that does not add significant weight to a service kit.
The 3734-TH is well suited for service calls involving recessed fasteners, panel fittings, and valve packing nuts commonly found in HVAC equipment, boilers, and plumbing rough-in work. The angle design allows a technician to apply torque from positions that a box-end or open-end wrench would not accommodate. It is sold individually and is appropriate for any trade professional who regularly works in tight mechanical spaces.
Designed as an OEM-style hand tool replacement suitable for general mechanical, plumbing, and HVAC service applications requiring a 1-1/16-inch angle wrench.
This wrench is intended for use by licensed trade professionals including HVAC technicians, plumbers, and pipefitters. Before servicing any fitting or fastener, shut off power, gas, or water supply to the affected system as applicable. Ensure the wrench opening is fully seated on the fastener before applying torque to prevent rounding. Do not use extensions or cheater bars that could overstress the tool or the fitting being worked.
