We have a vast range of trampoline springs. With accurate measuring you're likely to find a spring to fit your trampoline.
A Trampoline should have all springs attached and working, at the same tension, at all times. As soon as one spring is missing or over sprung it is recommended to stop using the trampoline until a replacement spring of the same size (length and diameter) is sourced and fitted.
How To Measure A Trampoline Spring
A trampoline spring is measured by removing a spring that is still in tight spring condition, off the trampoline. Run the tape measure from "hook end to hook end" and take the measurement in millimeters.
Also, measure the diameter of the spring. Sit the tape measure on the top of the spring and get a measurement from outside of the coils you may need to factor in a millimeter or two if the coils taper off at the ends.
It is recommended to buy more than one. Postage is almost always the same for a few.
