  • Patent number: 6523321
    Abstract: A joist hanger used to attach a joist to a support member or header designed to minimize the noise caused by the rubbing of the members of the connection, during loading. The joist hanger includes a seat and a pair of side walls extending upwardly in spaced relationship therefrom to receive the end portion of an joist. The bottom of the joist rests on the seat, and the side faces of the joist extend upwardly therefrom in spaced relationship from the side walls of the hanger. Inwardly projecting guides formed in the side walls of the hanger, hold the joist at selected points, maintaining the spaced relationship between the sides walls of the hanger and the side faces of the joist. The inwardly projecting guides can be formed with embossed portions connected to the side walls of the joist. The joist hanger is also formed with back flanges and top flanges that are relatively narrow compared to the back flanges.
