Heavy-Duty Security & Fire-Rated Compliance
- 3-Hour Fire Rating: UL listed for use on the inactive leaf of labeled fire door pairs. This ensures the door remains securely latched during emergency events, meeting strict municipal building codes.

- Extended 12" Reach: The 12-inch length offers superior leverage and accessibility, making it easier for personnel to operate on taller commercial doors compared to standard 8-inch bolts.
- Superior Bolt Throw: Features a 1-1/8" bolt throw, ensuring deep engagement into the strike plate to resist forced entry and door warping.
- Thru Bolts available: Rockwood SP1019
Versatile Installation & Architectural Finish
- Satin Chrome (US26D/626): Finished in a durable, corrosion-resistant Satin Chrome that seamlessly matches standard commercial door hardware and office aesthetics.
