We've paired our must-have porch swing hangers with our customer-favorite comfort springs to make your new porch swing easy to hang and as comfortable as possible. Our patented comfort springs are made with a high-strength steel, which is zinc-plated and clear-coated to provide protection against weather elements. The springs are designed to evenly distribute the weight for effective shock absorption, enhancing your comfort and protecting your overhead support. The 2 swing hangers are meant to withstand the wear and tear of indoor or outdoor use. The hangers are made with extremely strong and durable glass reinforced nylon around the metal which is in the eyelet of the hanger and the set is rated to hold 1500 lbs.
