The Rockwood 2845 Combination Flush Bolt Set provides fire-rated security for metal doors while improving daily door operation. Because it includes both top and bottom bolts, inactive doors stay secure, and active doors open smoothly with minimal effort.

When the active door is opened, the inactive door remains latched at the top until the top bolt is released by pressing the plunger button on the bolt face. Meanwhile, the bottom bolt operates fully automatically to provide added security and ease of use.

Bottom Bolt Features:

• Low closing force for smooth operation
• Fully automatic—opening the active door retracts the bottom bolt
• Override feature prevents damage if the bolt head is blocked from entering the strike
• Bolt head rod adjustable up to 3/4″ for precise installation
• Thermal lock automatically secures the inactive door under high heat conditions
• Designed specifically for metal doors

Top Bolt Features:

Additional Features:
