Rockwood 580 8" Heavy-Duty Surface Bolt | UL Fire Rated
The Rockwood 580 8" Surface Bolt is a rugged, high-security locking solution designed for commercial, industrial, and institutional applications. Unlike concealed flush bolts, this surface-mounted bolt provides a visible deterrent and easy operation for securing the inactive leaf of a pair of doors. It is UL listed for use on 3-hour fire-rated doors, making it a critical component for maintaining life-safety compliance in hospitals, schools, and retail corridors.
Industrial-Grade Security & Fire Safety
- 3-Hour Fire Rating: UL listed specifically for use on the inactive leaf of labeled fire door pairs, ensuring the doors stay closed and latched under extreme conditions.
- ANSI/BHMA Certified: Meets ANSI A156.16: L04161 specifications, guaranteeing superior strength and long-cycle durability in high-traffic areas.
- Extended Bolt Throw: Features a generous 1-1/8" bolt throw, providing deep engagement into the strike for maximum resistance against forced entry or door warping.
- Heavy-Duty Construction: Built with a 1/4" x 3/4" solid steel bolt, this hardware is engineered to withstand significant physical abuse without bending or failing.
Versatile Installation Features
- Dual Strike Options: Each unit includes both a universal top strike (for surface mounting on the frame) and a mortise bottom strike (for floor installation), allowing for flexible mounting configurations.
- Multi-Surface Fasteners: Furnished with both sheet metal screws (#10 x 1-1/4" FH SMS) and machine screws (10-24 x 1" FH MS) to accommodate installation on hollow metal or wood doors.
- Sleek, Visible Protection: The 8-inch length provides a professional, architectural look while remaining easy to reach and operate for facility personnel.
