Our hammock spring hanging kit includes 2-pieces of snap hooks, 1 spring and one 360° rotation hook. The comfortable springs are made of high-strength spring steel, zinc-plated and clear-coated for protection, durability and rust resistance. The swing swivel and snap hooks are made of stainless steel, offering corrosion resistance, high hardness and a non-toxic, pollution-free environment. The swivel hook allows for 360° rotation without tangling or twisting, while the snap hook securely clips onto hammocks or swing chairs. The tightly coiled springs effectively absorb shock, enhancing the comfort of your porch swing and protecting the overhead support. Safe and reliable, suitable for adults and children of all ages. Easy to install, you can easily attach this spring kit to your hammock chair within minutes without any tools. Specifically designed for hanging hammock chairs, swing seats, hanging chairs, hammocks, tents, punching bags or other heavy objects. Perfect for your patio, porch, horizontal tree logs or ceiling hooks.
