Technology has improved the durability and longevity of trampolines. Their surface is resistant to sun damage and the springs have been improved. Trampoline improvements have also decreased the overall weight of the device. While a lighter weight allows you to move its location more easily, it also makes the trampoline more susceptible to wind gusts and storms. Anchoring your trampoline will protect the users, and will help limit your liability should it end up down the street after a storm.
Order a trampoline anchor kit from a trampoline supply company.
Secure each of the four hooks with attached straps to the frame of the trampoline. Place the hooks at equal distances from each other to distribute the potential weight, or force, of the trampoline evenly.
Thread one end of each of the four straps through the eyes attached to the frame hooks. Thread the other end of the strap through the eye attached to one of the four ground screw augers and buckle the strap to connect each hook to an auger.
Screw each auger completely into the ground. Adjust each strap to equal tension.
Spotters are required for trampoline use. An additional person is required to hold the trampoline in place while you adjust the screw or strap tension will make your job easier and help avoid you pulling the trampoline off balance. Check with your homeowners policy to determine your liability for a guest's injury or a wind-borne trampoline.
According to the Trampoline Safety website, "If you anticipate severe winds, the trampoline should be moved to a sheltered location or completely disassembled." The American Academy of Orthopaedic Surgeons' Position Statement cites national and international research that "indicates that trampolines should not be used in the home environment." Recognising that there is a large market for home trampolines notwithstanding, the Position Statement cites guidelines that include the recommendations that any trampoline activity by children be conducted one child at a time, padding be used on all appropriate surfaces and always under the supervision of an adult.
