The Rockwood 2942 Automatic Flush Bolt Set provides reliable fire-rated security for wood doors while improving daily door operation. Because it includes both top and bottom bolts, the inactive door stays locked automatically, and the active door opens smoothly with minimal effort.

How It Works:
When the active door opens, both the top and bottom bolts retract automatically. Meanwhile, the thermal lock secures the inactive door under high heat conditions, helping to contain fire. If a bolt head is blocked from entering the strike, the override feature prevents damage to the door or bolts.

Key Features:

• Fully automatic—opening the active door retracts both top and bottom bolts
• Low closing force reduces effort to shut the door
• Bolt head rods adjust up to 3/8″ for precise installation
• Thermal lock automatically secures the inactive door under fire conditions
• Non-handed design fits doors that swing either way
• Compatible with No. 570 Dust Proof Strike
