Half of the final presentation board showing the final designs and functions of the RIPCORD Snow Tube Linking System. The Final design is basically a cheap way for kids to link there tube sleds together. Becuase of the strap system the clips can link to anything that they will fit around such as handles of other sleds. They can be linked in many arrangements as well. The linking system acts similar to a carrabeiner so the possablities are endless.
