Pemko 297AS Jamb Weatherstrip with Silicone Insert - Mill Aluminum for 3'0" x 7'0" Door
The Pemko 297AS is an architectural-grade perimeter gasketing set designed to seal the gaps between a door and its frame. This set is specifically sized for a 3'0" x 7'0" opening, containing one 36" header piece and two 84" jamb pieces. Constructed from high-quality mill finish aluminum and a high-performance Silicone bulb insert, the 297AS creates a tight compression seal that blocks drafts, moisture, and noise while maintaining life-safety certifications for fire and smoke.
High-Performance & Weather Defense Features
- Premium Silicone Insert: The silicone bulb is superior to vinyl, remaining flexible in extreme temperatures and offering excellent resistance to sunlight, ozone, and oxidation. It is ideal for high-performance settings that require frequent cleaning with disinfectants.
- Engineered Compression Seal: Designed for standard 1/16" gaps, this seal can effectively close gaps up to 1/4" deep, ensuring a weatherproof barrier even if the door is slightly misaligned.
- Fire and Smoke Certified: Rigorously tested under UL 10C for positive pressure and UL 1784 for smoke leakage, making it a critical component for fire-rated door assemblies.
- Hygienic and Durable: The silicone material is non-toxic, self-extinguishing, and impervious to fungus and mildew, ensuring it will not deteriorate under normal environmental exposure.
- Sound and Air Barrier: Tested to ASTM E-283 for low air infiltration and ASTM E90 for sound attenuation, significantly improving the energy efficiency and acoustic privacy of any room.

Pro-Tip for Perimeter Sealing
The Pemko 297AS is surface-applied to the stop of the door frame. For the best results, install the header piece first, followed by the jamb pieces. Adjust the slotted holes so the silicone bulb is slightly compressed when the door is latched. This "snug" fit is essential for achieving the rated smoke and air seal performance.
