Hager 872S Dark Bronze Aluminum Astragal | Black Neoprene Seal
The Hager 872S in Dark Bronze Anodized finish is a high-performance meeting stile astragal designed to seal the vertical gap between pairs of doors. Featuring a sleek aluminum housing and a 5/8" black neoprene flange, this astragal is the professional choice for eliminating drafts, light, and sound transfer in double-door applications. The Dark Bronze (duranodic) finish provides a high-end, architectural appearance that perfectly matches bronze storefront systems and commercial hardware.
Extreme Resilience for Demanding Climates
The Hager 872S is engineered to perform in the most unforgiving environments. The premium neoprene insert remains exceptionally flexible in extreme temperatures as low as -50°F (-45°C), ensuring that your seal will not crack or become brittle during harsh winter months. This resilience makes it ideal for exterior perimeters, cold storage facilities, and high-traffic commercial entrances where maintaining a consistent environmental barrier is critical.
Precision Engineering and Easy Adjustment
To ensure a perfect seal between door leaves, the 872S is designed with slotted mounting holes. This allow for precise lateral adjustment during installation, compensating for any door misalignment or natural settling of the building. Each unit is furnished with matching zinc-plated #6 x 5/8" pan head sheet metal screws to provide a secure and aesthetically cohesive installation on wood or hollow metal doors.
