Hager 835S Flat Bar Astragal, Prime Painted Steel, 7 or 8 feet

The Hager 835S is a heavy-duty Flat Bar Astragal engineered to provide a secure and fire-rated seal for the meeting edges of pairs of doors. Constructed from high-strength 1/8" thick steel, this surface-mounted hardware is an essential component for protecting against forced entry, weather infiltration, and the spread of fire. The 835S comes in a prime painted grey finish, making it ready for immediate installation or a custom topcoat to match your specific facility colors. Whether you are outfitting a warehouse, a mechanical room, or a commercial storefront, this astragal provides a professional-grade finish for double-door applications.

Security and Fire-Safety Protection

The Hager 835S serves two critical roles: physically securing the gap between double doors and maintaining the integrity of fire-rated openings.

• Forced Entry Deterrent: By covering the vertical gap between a pair of doors, the 835S prevents intruders from gaining access to the lock or latchbolt, effectively "shielding" the door's locking mechanism from tampering.
• Fire-Rated Compliance: This steel astragal is UL Classified as a Category J Gasket. It is approved for use on hollow metal doors rated up to 3 hours and wood composite doors up to 1-1/2 hours, ensuring your facility remains up to code.
  
• Heavy-Duty Construction: The 2-inch wide, 1/8-inch thick steel bar provides a rigid, durable barrier that resists bending and impacts in high-traffic commercial environments.
• Universal Application: Suitable for both new construction and retrofit projects, it is furnished with #10 x 1" sheet metal screws for a secure attachment to the door leaf.

Its pre-primed surface saves time on the job site, allowing for quick installation and painting to ensure architectural continuity throughout your facility.
