Ives FB41 Automatic Flush Bolt for Wood Doors — 3/4" Throw, UL Listed 90-Minute

The Ives FB41 is a fully automatic flush bolt system engineered for wood double-door applications. When the active door closes, the bolt extends automatically; when the active door opens, it retracts — no manual operation required. Available as a top-and-bottom pair (FB41P), top bolt only (FB41T), or bottom bolt only (FB41B), in seven finishes from Bright Brass to Matte Black. Non-handed. UL Listed for 90-minute fire-rated openings. Meets ANSI A156.3 Type 25.

Key Features

  • Fully Automatic Operation: Bolt extends on active-door close, retracts on open — no thumb turn or manual throw required.
  • 3/4" Bolt Throw with 7/8" Vertical Adjustment: Provides reliable strike engagement and installation flexibility to accommodate minor frame variations.
  • Low Actuation Force: Top bolt operates without spring tension, reducing wear and effort over the life of the hardware.
  • UL Listed — 90-Minute Fire Rating: Code-compliant for fire-rated wood door openings in commercial applications.
