The support has a slide way channel (4) for a roller shutter door, formed by two hollow walls (4a, 4b) each having an inner (14A, 14B) and an outer (14D, 14E) face. It also has a flat surface (14F) for fitting against a wall so that the channel lies parallel to the wall and leaves a gap between the wall and the facing surface (4E) of the nearest hollow wall which is sufficiently wide to receive the shutter edge if it jumps out of the guide channel. |
