Features: The replacement trampoline spring has high durability and weather resistance, providing you with the best possible and long-lasting bounce. Compared to regular trampoline springs, the silver spring features a tapered design with tight coils, giving the spring better elasticity and stretchability. The trampoline spring has two different ends; one is designed to be more curved to better grip the matching clips; the other end is less curved and is designed to insert into the metal frame. The replacement springs are the fantastic replacements for your broken, stretched, or even rusted springs; with the help of a trampoline spring puller tool, installation becomes much easier.
