ABSTRACT A roller door and frame combination, said roller door having a curtain with a plurality of parallel spaced-apart corrugations arranged parallel to the axis of rolling of the curtain, the frame being of the type having elongate channel members for slidably receiving each side edge of the curtain over a major length of the curtain and wherein the curtain is maintained in its corrugated shape by flexible wearing strips of material fastened to crests on one face of the curtain, at least one wearing strip being near one side edge of the curtain, and at least another wearing strip being near the other side edge of the curtain, characterized in that there is a resilient friction surface in each of the channel members for co-operating with the face of the curtain which does not have the wearing strips fastened thereto and being of such a size as to restrain the door against lateral back and forth movement in the frame and provide substantially uniform resistance to sliding of the curtain within the channel members should the curtain thickness change.
