Summit Supply’s Replacement Pendulum (SH-167) will save the cost and hassle of installing an S-hook. Makes attaching chains to swing hangers simple. Bolt pin has a tamper resistant head that requires an Allen wrench (H-175) to open and close. Our other replacement pendulum (SH-165) will save you time and money because you will not have to replace the whole swing hanger. These do require a clevis or “S” hook to install the chain.
