The method consists of fitting sections (2,3) to door (1) and frame on floor (4). The sections are rectangular, with one wall thicker than the others for fastening by screws (10). Special hinges (8) are used. Holes are provided in the outer wall of the sections to assist insertion of screws. A rigid strip may be passed through the section and screwed to the inner wall. |
