The Jones Stephens Lavatory Nut Removal Tool is the perfect tool to speed up difficult faucet removals and installations. It is designed to reach up under the sink into the hard to reach places for you. One side installs/removes most common lavatory faucet locknuts with ease. Slide the supply line through the tool and the other side becomes a 7/8" nut wrench, the common size for most 1/2" supply line nuts. The long 12" length is sure to reach behind the deepest sinks. Made of lightweight ABS plastic for corrosion resistance.
