How to measure trampoline springs
Wear gloves and safety goggles to protect yourself.
The springs on the trampoline can be rough on your bare hands, especially if there are no protective coverings on the hook ends of the springs. Wear gardening gloves or thick work gloves to protect your hands.
Get safety goggles so your eyes are protected in the event the spring flies in your face. Unhook the first spring from the trampoline with flat-head pliers.
