A B S T R A C T A goods-handling door of the raisable type, the door comprising a flexible or hinged curtain, optionally having horizontal reinforcing bars and capable of being wound, folded concertina-like, or displaced above the door, the edges of the curtain sliding between the side walls of vertical slideways which are spaced substantially further apart than the thickness of the curtain, or of the reinforcing bars, if any, with thrust means being provided in each slideway for thrusting the edge of the curtain against one of the side walls of the slideway. Each thrust means is constituted by an elongate element, is resiliently held in a horizontal position by a resilient hinge disposed between one of the ends of the thrust means and one of the walls of the slideway, and is shorter than the spacing between the side walls of the slideway so as to leave a gap substantially equal to the thickness of the curtain or to the thickness of a reinforcing bar, if any.
