Suspend your hammock chair from the ceiling instead of a stand. Can’t find a 4 inch secure surface? No problem! The adapter reduces the hanging space to 1.5 inches. The included chain is 33” long, but you can use as much of it, or as little of it as you’d like to match your needs. The swivel hook set with adapter is designed with industrial bearings that provide a secure and flexible hanging point for our chairs, while rotating without having to worry about stress on the hanging point. The adapter uses the hardware of the swivel hook, as well as adds a few more screws for extra stability. Combined with the adapter, the total weight the swivel hook will hold is 250lbs. This adapter is designed to work specifically with the Swivel Hook from Byer of Maine.
