ESKADE-SYSTEM barrel vault skylight assembly instruction

Before installing the lower vault profiles, it is necessary to mark their exact position that matches perfectly the width of the polycarbonate sheets. Otherwise it would be necessary to cut every sheet to a correct dimension, which would prolong and hinder the process of installation. It might even cause the polycarbonate sheets to run out before the installation is completed. For screwing in the screws, an "8" spanner is most commonly used.
