This universal trampoline enclosure system is designed to fit most 14 ft. round models that have 4-legs. The patented fiberglass G3 poles keep the system upright and around the jumping surface area, while the foam sleeves can help mitigate the impact from any unexpected collisions. This system connects to the 14 ft. trampoline's legs by using sturdy U-bolts to keep the enclosure firmly in place.
