The Pemko 357 Overlapping Astragal provides a high-quality solution for sealing gaps in double-door entryways. By overlapping the inactive door, it blocks drafts, light, smoke, moisture, and noise while creating a continuous, secure seal. As a result, it improves energy efficiency, enhances security, and reduces sound transfer between spaces.

In addition, the system offers versatile options, including a no-drill (ND) model and the use of S88 adhesive gasketing. It can be custom-cut to fit your doors and paired with optional Silicone Teardrop Weatherstrip for superior sealing performance. When installed on fire doors, it must comply with NFPA 80 requirements, and a door coordinator is needed when both doors are active. Surface-mounted with pre-drilled holes and supplied screws, the astragal provides easy and reliable installation. This system is compliant with smoke, fire, and air infiltration standards and can also be leadlined if needed.
