Our replacement jumping mats proudly use a grade #1 black non-abrasive Permatron® type mat material and are constructed using only the finest heavy-duty thread and rustless hardware connection v-rings available for added mat life. Measure your frame from one side to the other side. This is your frame size. Measure your old mat from edge to edge, not including v-rings. This is your mat size. Measure one of your springs, including both hooks. This is your spring length. Now, count all the springs holes in the frame and see if it matches the number of v-rings on the mat and number of springs you have for your trampoline. This is your spring count. REMEMBER: Measure & Count twice so you only have to order ONCE!
How to Measure for a Round Trampoline Mat
Measure the frame. You will measure across the middle of the trampoline from outside frame to outside frame, straight across the middle. To get the most accurate measurement, you should measure in 2 spots as shown in the diagram below.
Measure the springs. You will take a spring OFF of the trampoline, make sure that it is fully recoiled and measure it from hook-end to hook-end. It is very important that you not use a stretched-out spring and that the spring NOT be attached to the trampoline to get an accurate measurement.
Count the springs. You will count the spring holes around the top of the trampoline frame. We suggest that you also count your springs to make sure that none are missing.
Measure the mat. If possible, it is best to measure the mat while still attached to the frame. You will measure the mat from hem to hem straight across the middle, DO NOT INCLUDE THE V-RINGS. Note the EXACT inches of the measurement.
