One of our primary goals is to keep children safe. The Jensen Non Wrap Swing Hanger is designed to help keep stress from impacting the chain and fasteners on swings. This hanger fits a top rail with an outside diameter of 2-3/8-inches. The innovative non-wrap design prevents swing chains from becoming caught at the top of the swing. It achieves this with use of a nylon sleeve. The steel hanger rests on the outside and fits in the molded grove. This allows the hanger to spin on the top rail while being completely safe for commercial use. The tensile strength on this product is 5000 lbs. Please carefully observe all safety procedures.
