Hager 837SDV-84" Dark Bronze Astragal with Vinyl Bulb Seal
The Hager 837SDV is a high-performance commercial door astragal designed to seal the gap between pairs of doors. Featuring a durable Dark Bronze Anodized Aluminum housing and a flexible vinyl bulb insert, this 84-inch security and weather seal prevents air infiltration, smoke transfer, and light gaps. It is an essential component for maintaining energy efficiency and meeting stringent building codes in commercial, institutional, and industrial settings.
Advanced Fire and Life Safety Compliance
The Hager 837SDV is rigorously tested and UL Classified for use on a wide variety of fire-rated openings. As a Category H and J gasket, it is approved for use with listed steel frames and hollow metal doors with up to a 3-hour fire rating. It is also compatible with wood and plastic-covered composite doors rated up to 1-1/2 hours, and wood core doors rated for 20 minutes. This versatility ensures your facility remains compliant with local fire marshal requirements.
Precision Engineering and Easy Installation
This astragal is designed to be attached to the edge of the door, providing a consistent seal that moves with the door leaf. It is furnished with high-strength #8 x 1" Pan head sheet metal screws for a secure, permanent mount. The 1-3/16" width provides ample coverage for standard door gaps, while the Dark Bronze finish offers a professional, low-profile appearance that coordinates perfectly with dark-colored commercial storefronts and hardware.
