摘要

The screen consists of a waterproof panel with a frame in sliding sections made from 25 cm and 20 cm square welded tubes. The frame sections are connected by threaded rods and adjusted by means of nuts (5, 6) so that the screen fits into the door or window opening. The edges of the screen are fitted with rubber seals in the form of strips with round edge beads.
