This tool is made to connect at the top of your carbon fiber vacuum poles to reduce the outgoing airflow when using a blower system. A tighter air stream at the top increases the blowing impact. This is similar to partially putting your finger over the end of a water hose and watching the water shoot out faster.
The open silicone end will fit our 2" push fit poles. If you want to connect this to the Elite Pole Set you'll also need a SkyVac®️ Carbon Fiber Spigot Adapter.
