According to your results select the Upper Bounce mat that fits your trampoline.
Example:
- Frame size: 14-feet
- V-ring count: 72
- Spring size: 7-inch
- You will need to select the Upper Bounce Trampoline Model # UBMAT-14-72-7.
For Your Information:
In order to figure out the mats actual measurement.
Measure your trampoline from frame to frame, subtract two times the spring measurement - (Spring size - from hook to hook), Then subtract 5 inches. The result is the actual mat size from V-ring to V-ring straight across.
Example: Frame size 14-feet, subtract 7.5-inch for the spring x 2 is 15 inches, subtract an additional 5 inches = 12-feet with 4-inch. This is the actual mat size with the V-rings.
