Instructions
Remove two or three springs from the trampoline.
Place the ruler next to the first spring. Use inches as your unit.
Measure the total distance from the end of one hook to the end of the other. Record your measurement.
Measure the other spring or two to ensure accuracy. If the first spring is stretched out, compare with others to get the right size. Trampoline springs usually come in
4 3/8-inch to 10-inch sizes.
