Underhill introduced the Extender, a solution for buried quick coupler valves with difficult-to-open keys. The Extender remedies having to dig up and raise the valve to make the key operational. Three models are available to fit any quick coupler key (3/4”, 1” and 1-1/2”). The Extender raises the quick coupler key an additional 4 inches. The Extender is solid brass with a built-in handle.
