The Air Comfort Trampoline Wind Stakes Anchor Kit ensures a breezy day will never blow your trampoline away. 4 heavy-duty galvanized steel stakes universally connect with the base of each leg to prevent flipping or moving during adverse weather conditions. At 2.5 inches in diameter each, the stakes are also rust-resistant. Soil type and installation methods will greatly impact the effectiveness of this stake kit. In areas with sand, loose soil, or high wind, two wind stake kits are recommended for use.
