Hager 891S Weatherstrip – Dark Bronze Aluminum with Vinyl Insert, 3'0 x 7'0

The Hager 891S is a surface-applied perimeter jamb weatherstrip designed for standard commercial door openings sized 3'0 x 7'0. It features an extruded aluminum housing in a dark bronze anodized finish with a vinyl insert that compresses against the face of the door when closed, creating a seal against air infiltration, dust, light, and moisture. This profile mounts to the door stop on the head and side jambs, providing a clean, low-profile solution for commercial perimeter gasketing applications.

As a Hager 800S-series jamb weatherstrip, the 891S is well-suited for interior and light exterior commercial openings where a coordinated dark bronze appearance is required to match other architectural hardware finishes. The vinyl bulb insert provides reliable performance in moderate-temperature environments. For openings in cold climates or high-cycle applications, upgrading to a neoprene, polyurethane, or silicone insert material is recommended, as vinyl can harden and lose sealing properties below freezing.

Key Features and Benefits

• Dark bronze anodized aluminum housing — coordinates with dark bronze finish door hardware and frames
• Vinyl insert — compresses against door face to seal air, light, and dust infiltration
• Surface-mounted profile — attaches to existing door stop; no frame modification required
• Pre-cut 3'0 x 7'0 set — sized for standard commercial single door openings; ready to install
• Perimeter jamb weatherstrip — for use on head and side jambs of commercial door assemblies

Typical Applications

• Commercial office and institutional interior doorways requiring air or dust seals
• Light exterior commercial openings in moderate climates
• Replacement weatherstrip on existing hollow metal or wood door frames
• Openings where dark bronze finish coordination is specified
• New construction and renovation projects requiring perimeter door gasketing

Material and Climate Considerations

Vinyl insert gasketing performs well in moderate temperature environments. Per industry guidance, vinyl becomes stiff and may crack in sustained sub-freezing conditions, reducing its weathersealing effectiveness over time. For high-performance cold-climate or exterior-exposed applications, consider specifying a comparable profile with a neoprene, polyurethane, or silicone insert, which maintains flexibility and seal integrity through a wider temperature range. Hager, Pemko, and National Guard all offer compatible perimeter weatherstrip profiles with upgraded insert materials for demanding conditions.

Technical Details

The Hager 891S is a high-performance surface-mounted weatherstrip designed to provide a superior perimeter seal for commercial, industrial, and institutional door openings. Engineered with a durable Dark Bronze (D) finish and a high-grade Vinyl (V) insert, this gasketing solution is specifically built to block drafts, light, sound, and moisture while maintaining critical fire and smoke safety ratings. Whether for exterior doors facing extreme cold or interior fire doors requiring smoke containment, the 891S delivers a professional, long-lasting seal.

Extreme Weather Resilience

The Hager 891S is the premier choice for facilities located in harsh climates. Unlike standard seals that become brittle and crack, the vinyl insert in this gasketing is chemically formulated for maximum environmental range:

• Extreme Cold Performance: Remains flexible at temperatures as low as -40°F, ensuring a tight seal even in the dead of winter.
• Heat Resistance: The specialized vinyl resists high-heat degradation, maintaining its profile and sealing properties in sun-exposed or high-temperature environments.
  
• Acoustic & Air Infiltration: Successfully tested in accordance with ASTM E283-91, effectively reducing air and smoke leakage to improve energy efficiency and occupant comfort.

Precision Engineering & Installation

Hager has optimized the 891S Series for the professional installer and facility manager:

• Slotted Mounting Holes: The aluminum housing features slotted holes, allowing for easy adjustment and fine-tuning during installation to ensure a perfect contact seal against the door.
• Complete Hardware Kit: Furnished with zinc-plated #6 x 5/8" pan head steel screws, providing a secure and corrosion-resistant attachment to the frame.
  
• Dark Bronze Aesthetic: The Dark Bronze anodized finish provides a high-end, architectural look that blends seamlessly with dark-colored storefronts and wood-grained doors.
