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). We also supply a hook for fitting the springs which we recommend. The numbers of springs required for each trampoline are Dinamic 118, Goliath 112, 77A 100, Junior 78 and Grasshopper 60.

Price per spring.
