61666 is designed to connect industry standard home shop vacuum ends measuring 2.25" to a second hose with the same 2.25" industry standard end. This solution permits a second hose being attached as an extension o the hose commonly provided with the vacuum that often falls short in length of the needs of the application. The 61666 can also be used to connect Quick Click dust collection hoses to the hose provided with the vacuum enhancing the potential use of the vacuum as a dust control solution. Compares very favorably with Shop-Vac item 88-1040-01.
