Rockwood 2842 Automatic Flush Bolt Set | For Fire-Rated Metal Doors
The Rockwood 2842 Automatic Flush Bolt Set is a premium architectural hardware solution designed to provide seamless security for pairs of fire-rated metal doors. Engineered for fully automatic operation, this set ensures the inactive leaf is securely latched whenever the active door is closed, and automatically retracts both the top and bottom bolts when the active door is opened. UL Listed for up to 3 hours, it is a critical component for maintaining life-safety compliance in commercial and institutional buildings.
Professional Security & Life-Safety Compliance
- Fully Automatic Functionality: Eliminates the risk of human error by automatically engaging and retracting. This makes it an ideal choice for ADA-compliant openings and high-traffic corridors where manual bolts are impractical.
- Thermal Lock Safety: Features an integrated thermal lock that automatically deadlocks the inactive door when subjected to high heat (230°F), ensuring the door leaves remain closed to contain smoke and flames during a fire.
- Equipment Protection: The built-in override mechanism prevents costly damage to the door and hardware. If the bolt heads are obstructed and cannot enter the strike, the mechanism gives way rather than bending the rods or damaging the door skin.
- Precision Fit: Each bolt features a 1-1/2" adjustable rod, allowing installers to fine-tune the engagement for a perfect fit against the header and floor strikes, even if the door is slightly misaligned.
- Low Operating Force: Designed with a 5 lbs. maximum closing force, ensuring the door closes and latches with minimal effort, reducing wear on door closers.
