Abstract
Abstract This invention relates to insulated hanger strap, designed to support ductwork, pipes, and the like. A flexible sheet metal strip is provided with holes through which fasteners may be inserted and be secured to a supporting structure. An elastomeric strip completely covers one side of the sheet metal strip, and has flanges formed on its longitudinal edges which cover the edges of the associated sheet metal strip. Channels are formed in the flanges of the electronic strip to receive the respective metal strip edges, thus maintaining the metal strip and the elastomeric strip in attached relationship.
