Designed by us on a 3D printer. This is a PLA plastic 3D printed adaptor. There are three types. The slide in adaptor fits into most inflatable boards. The kayak/canoe adaptor can be strapped around just about any board, canoe, or kayak (straps not included). The Flip Lock is designed to fit into inflatable paddle boards that have the Flip Lock type of fin box.
Do not use in shallow waters. Do not store in vehicle or an area with excessive heat.
The adaptor is printed in a random color (usually, white, blue or black)
