The Pemko 355_S T-Shaped Astragal with Silicone Insert is a surface-mounted solution for the single active door in a pair of double doors. By sealing the gap between doors, it blocks smoke, drafts, sound, light, and insects, creating a continuous, tight seal for improved safety and comfort.

Additionally, it features a clear anodized aluminum casing with a durable silicone insert, making it strong and long-lasting even in harsh conditions. When the doors close, the silicone compresses against the inactive door to ensure a firm seal. Furthermore, a door coordinator is needed when both doors are active, and fire door installations must follow NFPA 80 requirements. For environmentally conscious projects, an Eco-V gasketing option is also available.
