<p>The case holding the filling for a leaf on a door is peripherally bounded by walling sections, formed by strips from the rear walling bent at right angles to the required width. The corner areas are sealed from water spray. In each corner area a lengthways slotted filling piece is thrust in, far enough to fit against the case rear walling providing clamping against the end faces of the walling sections. It can be in the form of angular battens, spaced according to the wall section thickness, monolithically interconnected in the apexes of the inner shanks.</p> |
