Our tapered steel joiner allows you to join two hoses for the Cyclone 3600 together. The Cyclone comes with a 16 foot standard hose. The coupling will allow you to join this hose with the 32ft (add on) hose for the Cyclone. This cuts down on having to move the machine constantly as you are working, and also provides versatility of being able to take the hose up a ladder and use the nozzle and suck the debris out.
