Neoprene hangers consist of a steel frame containing a neoprene isolation element. This element is molded with a rod isolation bushing that passes through the hanger frame. It is used for bolting or attaching to the ceiling flat iron straps, wires, rods and steel runners. It is used to reducing noise and minor vibration transmission. Hangers are noise breaks for use with wire, chain or horizontal screws for hung ceiling applications.
