Trolley padding kit. Consists of a foam tubing with 2 600D nylon protectors with Velcro fastener. This padding can be mounted on any Optiparts trolley. It protects the hull and makes the surface slippery for easy launching. Be sure to use the Bow Wow to prevent damages. The padding runs over the full width of the trolley, so the middle is protected when turning the hull upside down.
