<p>A door release having a metal frame (1, 3, 4) and a filling, in particular for livestock barns, is rendered hygienic and totally resistant with respect to corrosion and rotting in that it is covered on both sides with panel-type claddings (9, 10), the borders of which are held and covered, laterally and at the top, by sheet-metal profiles (7) which are fixedly welded on the frame (1, 3, 4). The inner cladding (9) preferably consists of a wooden panel and the outer cladding (10) preferably consists of rebated boards. A Z-profile strip is welded on at the bottom. The door release has, at the top, a window cutout which can be closed by a slide (13), which can be lowered between the claddings (9, 10) and consists of acrylic glass, to be precise with the aid of a belt roller. <IMAGE></p> |
