4 large, heavy-duty "cork-screws" twist into the ground. A sturdy strap secures to each cork-screw and attaches to the frame of the trampoline. When properly installed, the trampoline will be divided into 4 equal sections to evenly distribute the tension and safely secure your trampoline and enclosure to the ground.
Helps prevent strong winds from moving/flipping your trampoline. (Damage to the trampoline/enclosure caused by wind is not covered by warranty. Protect your investment!)
