This trampoline replacement mat is made out of Grade A polypropylene. It is considered to be a 12' mat it has 96 triangles. JumpKing made a trampoline that had 96 rings with 8.5" springs and the frame measured about 13'9-14'. This is the replacement mat for that trampoline frame. There are other brands this mat also fits.

Optional Sunguard "recommended" Description: The SUNGUARD is a strip of webbing stitched "over" the hem, the outside edge of the trampoline mat. This provides protection against premature Dry-Rot/Ageing from the Suns UV rays. This SUNGUARD will increase the life of your trampoline mats stitching for several years. This can be added to replacement mats. Colors May Vary!

HOW TO MEASURE ROUND BEDS

If your frame is assembled!

1. WITH A MEASURING TAPE THE FULL LENGTH (DIAMETER) OF YOUR TRAMPOLINE, MEASURE ACROSS THE MIDDLE, FROM OUTSIDE TO OUTSIDE OF THE FRAME. NOTE THE EXACT INCHES. (The measurement of one leg post to the opposite leg post will help insure you are measuring across the middle of the trampoline.) THIS IS A 12 O'CLOCK TO A 6 O'CLOCK MEASUREMENT.

2. MEASURE AGAIN ACROSS THE MIDDLE, THE DIAMETER OF THE FRAME, BUT WITH A 9 O'CLOCK TO A 3 O'CLOCK MEASUREMENT. NOTE THE EXACT INCHES. (Do not round off or convert to feet and inches.)

3. IF YOU HAVE YOUR MAT (AND IT DOES NOT HAVE A TEAR); MEASURE JUST THE BLACK PART, EDGE TO EDGE. DO NOT INCLUDE THE TRIANGLES. MEASURE TWICE LIKE STEPS ONE AND TWO DESCRIBED. NOTE THE EXACT INCHES.

4. COUNT HOW MANY SPRINGS IT TAKES. COUNT HOW MANY SPRING HOLES IN THE FRAME FOR MORE ACCURACY. (Then count how many springs you have, in good condition, recoiled and with lots of tension. You may be missing springs or want more tension)

5. TAKE A SPRING OFF THE TRAMPOLINE & MEASURE IT INCLUDING THE HOOKS TO DETERMINE THE CORRECT LENGTH. (The spring coils must be fully recoiled to obtain the proper length.
