Install/special instructions:    Simply slide the adjustable attachment point around to your back or other preferred point for paddling out. Can be worn alone or over waist harness or PFD. We recommend using the bungee as Wing Leash only and not as a board leash – we cannot warranty board use for Windsurfing and SUP Optional stainless steel quick disconnect swivel clip for wing attachment allows you to separate yourself from the wing, either in the water if any situations were to arise (possible at times to use it as a quick release) or out of the water so you can stow the harness and wing separately. Put it on the harness side to keep your leash with the wing, or on the wing side to keep the leash with the harness, or both with two! It also works as a swivel, for less chance of raveling, especially during aerial maneuvers. 2 1/2” long x 1 1/8” wide x 1/2” thick with 1/2” Eye
