<p>The assembly of profiled members forms external woodwork, having a base member (1) and a secondary one for a doorway, both of which can be increased in width, while a further member is included for the formation of mullions, transoms and intermediate uprights in a large fixed frame. An auxiliary member fits in a groove in the frame, and another deflects rain from the doorway. The base member is reversible, so that it can be used both in fixed and opening components. The secondary and further members fit on the base member, and the last-named can be installed at 45 degrees to the others.</p> |
