7 Inch Domestic Trampoline Springs
These replacement trampoline springs are suitable for any trampoline designed to use a 7" spring.
You will need to measure the spring from one side of the metal hook to the other to determine which size spring you need. If your springs are stretched, it is best to measure a few springs so you can be sure that you are buying the correct size.
Alternatively, if you still have the instructions that come with the trampoline, it should specify what size of spring is used.
