<p>The wooden window or glazed door section frame is made up from shaped interconnected battens (1), with screws (8) at the ends connecting them to plastic cylinders (6). The cylinders and screws are arranged on orthogonal lines, and inserted into fitting holes previously made in the battens. There can be four or more battens, shaped to incorporate a stop profile, with their ends serving as cross battens. The battens may have lugs (4), corresponding recesses or slits being formed in the upright battens.</p> |
