Jump Mat for 13 ft Trampoline Frame with 80 eyelets (for 5.5” springs)

To correctly measure the Jump Mat, you need to measure the frame size of your trampoline. You also need to measure the spring size of your springs from hook to hook ensuring it is not stretched. The most usual lengths are 5.5 inches, 7 inches or 8.5 inches. The number of eyelets on your mat can be counted also to get best fit, however, please note that if this number differs by a few or even up to 8 or 10 from universal replacement you can just space the springs out and it will still be a successful replacement fitting.
