The Keystone BOX/K 200 lintel is ideal for supporting openings in 200mm wide solid walls. It features perforations along its length that act as a plaster key, aiding in adhesion and finish quality. This lintel is designed to carry the full load of wet masonry immediately upon installation, ensuring dependable structural support. For best results, the BOX/K 200 lintel must be installed with a minimum end bearing of 150mm on either side of the opening, securely bedded on mortar.
