Carefully fix metal spring clips into the back of the louvre. Position clips inside tube or hole and push firmly until louvre is flush with brickwork or inside face. We recommend you mastic around the inside edge of the louvre for extra adhesion to brickwork (especially with 150mm (6″) diameter tubes and holes).
