We recommend steel springs for all competition use trampolines and either steel or elastic springs for schools and institutional use (elastic springs will not “pinch” you like steel if you contact them).
Grasshopper & Junior springs are 7″ long, all others are 10″ long.
Sets of springs for each of our trampolines are listed below. These will also fit other makes of trampoline.
Both size springs are also available individually and can be ordered in any quantity.
