SkyBound 3.5 Inch Replacement Trampoline Springs - Set of 12

[HEAVY-DUTY STEEL] Galvanized steel trampoline springs feature a zinc plating to protect against corrosion and rust caused by natural acids, moisture, and oxidation. [MORE SPRING FOR YOUR BOUNCE] Thicker gauge steel, greater coil count, and wider taper. These reinforced trampoline springs not only replace your worn-out springs, they enhance the whole bouncing experience! [OVERSTRETCH PROTECTION] If your SkyBound trampoline springs break, come loose, or become overstretched within 6 months of use, SkyBound will replace them free of charge. [SIZE MATTERS] We recommend double checking your spring size before ordering as they may have stretched over time. Remove at least 3 springs and measure from end to end to find an average.
