The AeroPole 30″ Half Pole is an add-on accessory to the Aeropole System Kit for creating air-filled balloon columns and arche frames and features one female end fitting and one male end fitting. If the standard 5ft poles are too short and 10ft is too tall for a column, using a 30″ Half Pole with a single AeroPole pole gives you a 7.5ft tall column. Perfect for an 8ft ceiling.The Half Pole is designed to insert into the Starter Pole (the first pole coming off the base plate) and is designed to fit into the other Splice Poles to create the frame of the design. This pole can be used to extend the length of your AeroPole System Kit.
