Hager 891S Perimeter Weatherstrip | Mill Aluminum with Neoprene Insert
The Hager 891S is a professional-grade commercial door weatherstrip designed to provide an airtight seal around the head and jambs of a door opening. This model features a heavy-duty mill finish aluminum housing paired with a premium black neoprene insert. Engineered for the most demanding environments, the 891S creates a high-integrity barrier that blocks air infiltration, sound, and hazardous smoke, making it a staple for commercial, industrial, and institutional entryways.
High-Performance Neoprene for Extreme Conditions
Unlike standard vinyl, the black neoprene insert in the Hager 891S is engineered for superior resilience. It remains fully flexible in extreme cold down to -50°F, ensuring the seal does not crack or fail in freezing climates. Neoprene also boasts high heat resistance and durability, allowing it to maintain its shape and sealing properties through years of heavy-duty cycles.
Certified Fire and Smoke Protection
The Hager 891S is a critical component for life-safety compliance. It is UL Classified and has been fire-tested in accordance with UL10C, making it suitable for use on Category H and J doors. Furthermore, it meets ASTM E283-91 standards for air and smoke infiltration. This makes the 891S an essential choice for fire-rated corridors in hospitals, schools, and high-rise office buildings where preventing the spread of smoke and toxic fumes is mandatory.
