A Better Spring:
Most trampoline retailers use the same spring: it's an 8.5" long, 1" thick, coil-out-the-side spring. It's not a bad spring, but it's not the best spring.. like we use at Dana Playground! Our spring does a better job of distributing energy into the middle of the spring, which puts less stress on the hook and gives a better bounce!
- 8.5 length (some use much shorter springs or 'bungee' material)
- Higher coil count (more coils = broader range of energy)
- Thicker spring (standard is up to 1", ours is 1 1/8".. much stronger)
- Hook from center (much less likely to bend or break the hook)
- More of them: 104 on our 14 ft. units! (others use 80 - 96 springs)
