Trampoline Springs Set of 20, 5.5 and 7 with Spring Tool for JUMPZYLLA, Skywalker, JumpKing, UpperBounce, SportsPower, BCAN

Thickened steel spring, 20,000 tensile tests, and super elasticity characterize the new product. The springs are made of heat-treated high-quality galvanized steel, upgraded to thickened steel, and coated with a new safety coating to prevent rust caused by natural acids, moisture, and oxidation, ensuring the springs' safety in wet weather. [New Material Upgrade]

The 3mm thick-plated steel wire is thicker than 80% of springs, tightly coiled (no longer shortened after 4-7 times of compression), and strong and wear-resistant, achieving a strong pulling force without deformation and not breaking after stretching 40-50K. After 5,000 professional jump tests, Ctgsas trampoline springs have no breakage or deformation, ensuring the user's safety when bouncing. [Protect Every Safe Jump]

Before purchasing, customers are advised to measure the length of the original unstretched spring from one end to the other, or measure the average of more than 3 used springs, as they may stretch over time. [Measuring Spring Length]

The spring pulling tool features a triangular closed-loop design, made entirely of thickened stainless steel with a gold-plated surface. It is an excellent auxiliary tool for installing trampoline springs, more sturdy and comfortable to use, and protects the user's hands from damage. It also helps save a lot of time and makes it easy to replace springs. [Spring Pulling Tool For Easy Installation]
