Adjustable Wrench Function

The Superior Tool 3840 is an adjustable wrench designed to remove or install drains and traps. Its adjustable mechanism fits pipe sizes from one to three inches. Plumbers and maintenance technicians use it for residential and commercial drainage work. The zinc construction provides corrosion resistance for wet environments.

Ideal For Drain Service

This tool suits professionals servicing sink, tub and floor-drain assemblies where a fixed wrench cannot engage the trap nut. It is not for buyers who need a pipe wrench for gripping round pipe stock, nor for technicians requiring a basin wrench to reach nuts behind deep cabinets. The adjustable jaw does not replace a strap wrench for polished or fragile finishes.

One-To-Three-Inch Capacity

The adjustable range of one to three inches determines whether the wrench fits the trap nuts on a given job. Verify the nut size before purchase to ensure the jaw opens wide enough. No other specification overrides this fit requirement.

Questions about this item

What size range does the adjustable wrench cover for drain traps?

The wrench adjusts from 1 to 3 inches to fit a variety of drain and trap nuts.

How do I set the jaw width before turning a drain nut?

Turn the knurled thumb screw to open or close the jaws until they grip the nut flats snugly, then apply torque.

Will the zinc coating wear off with repeated use on corroded fittings?

The zinc finish resists rust under normal plumbing conditions; wipe clean and apply light oil after use to extend its life.
