Abstract: A flexible multi-strip closure is supported in a vertically hanging position by means on horizontally oriented structural beads attached to each strip, which beads are retained in a horizontally oriented, inverted U-shape channel which includes an entrapment portion for supporting the beads against vertical forces and at least one lip to eliminate stress concentrations in the flexible strips when they are flexed. Releasable means are provided adjacent at least one end of the channel to restrict horizontal movement of the beads and to allow removal of the beads with their attached strips for cleaning and replacement.

Abstract: Strips of heavy transparent plastic are suspended in a doorway with the edge of each strip overlapping an adjacent strip to completely close the doorway in a manner which minimizes heat transfer through the doorway while permitting hand-free movement through the door. The strips are suspended by loops formed on the upper end of each strip. Various loop constructions and overlap arrangements are disclosed to facilitate the mounting of the strips.
