Rockwood 2845 Combination Flush Bolt Set | For Fire-Rated Metal Doors
The Rockwood 2845 Combination Flush Bolt Set is a specialized architectural solution for pairs of hollow metal doors. This set combines a self-latching top bolt with a fully automatic bottom bolt, providing a unique operational balance: the door remains securely latched at the top even when the active leaf is open, while the bottom bolt retracts automatically to provide a clear, hazard-free threshold. UL Listed for up to 3 hours, it is ideal for schools, hospitals, and commercial corridors.
Professional Security & Life-Safety Features
- Self-Latching Top Bolt: Automatically engages when the inactive door closes. It stays latched when the active door is opened, requiring a manual press of the integrated plunger button to release, providing enhanced control over the opening.
- Fully Automatic Bottom Bolt: To ensure ADA compliance and a clear floor path, the bottom bolt automatically retracts whenever the active door is opened.
- Thermal Lock Protection: Features an internal thermal lock that automatically deadlocks the inactive door under extreme heat (fire conditions), ensuring the door leaves stay closed to contain smoke and flames.
- Damage-Resistant Design: The built-in override feature prevents damage to the door or hardware if the bolt head is blocked from entering the strike.
- Adjustable Precision: Includes an adjustable bolt head rod (up to 1-1/2") to ensure a perfect, snug fit even if the door or frame is slightly misaligned.
