Move your Vuly trampoline as if it weighs nothing at all with the Thunder Pro wheels. This set includes two wheels to shift your medium Thunder Pro in the most efficient possible way. The wheels help move the trampoline to a spot with shade or allow you to mow underneath without disassembly. Simply attach to the frame and pull back on the levers to lift and move with a push. After moving the trampoline to the desired position, the wheels should be removed.
