If your trampoline has a 15 foot diameter frame with a 3 arch safety enclosure systems, then this is the right net for you. This is called a sleeve net because it attaches to your top arched pole by way of a sleeve sewn into the top of the net. To install you simply take apart one end of your arch, slide the sleeve over the top arch pole and then re-attach. At the bottom you simply attach the clips to the v ring on the jumping surface and then reinforce by threading the included ropes around the perimeter. Detailed instructions are included with the net.
