Customised installations

These instructions refer to our standard installation. For other solutions such as curved ceilings, closures and door liners, contact our support.


When the Ribs are installed with the spring clips, they can be demounted by gently pulling close to all the points of connection (U-FIX + spring clip), starting at one of the ends. Do not try to pull down the whole Rib by pulling at one of the ends only.


In the case of a re-installation of a removed Rib, be sure all spring clips are properly aligned with the center of the holes in the BASE-C profiles before pressing firmly home.
