Special Note The Q Foam material used in the V-shaped sealing strip may have pronounced creases after packaging. This affects appearance slightly, but does not impact the sealing performance. Strong Adhesive Grid-backed adhesive provides a firm, long-lasting bond with high flexibility. The strip resists degumming and maintains a good seal over time. For best results, do not remove or tear off the backing within 14 hours after application to allow full adhesive strength.
