Introducing the Adapter for installing the ProFlex Trampoline Basketball Hoop onto the Octagon Kit. This adapter is exclusively designed for use with 12' or 14' round JumpSport Classic and AlleyOOP Safety Enclosures when the Octagon Kit is installed. Please note that it is not compatible with other brands of enclosures or JumpSport/AlleyOOP 10'x17' trampolines. Trampoline, Enclosure, Octagon Kit, Hoop, and Backboard are all sold separately. This adapter is a necessary component when installing both the Octagon Kit and Proflex Basketball Set, but it is not required for Octagon Kit installation alone.
