It's Easy To Get Hooked! Our stainless snap hooks make it easy to choose the right height, just for you! You just snap your rope to the 7' or 6' ring and start getting the air that you crave! The hooks also act as like a fuse that will safely release the ski rope if the load exceeds approximately 750 lbs, so the pylon will continue to stay standing for your safety (as opposed to the other brands that use a "trailer hitch ball", which don't have any safety release capability). The pylon can tow a 250 lb skier without even breaking a sweat!
