The TB25KO drop bolts represent true engineering innovation, design excellence and the superior quality customers have come to expect and demand from Lockwood. Designed for use on swing-through, double-action doors, these drop bolts are ideal for applications where an electric strike is impractical. The TB25KO offers a unique mechanical override designed to use with a euro profile cylinder.

• High Security. Bolt is deadlocked in the extended position
• Mechanical key override (Euro Profile Cylinder)
• Bolt position monitored
• Door position monitor with integrated magnet into the strike plate (no need to install a separate reed switch)
• Multiple Orientation, drop bolts will work horizontally or vertically
• Power to Lock/ Power to Open
• Continuously Rated Solenoid
• Tamper Proof. The lock cannot be defeated by slipping a metal object between the lock and striker plate
• Intelligent Electronics. These intelligent bolts will attempt to re-close the bolt 8 times, allowing time for swing through doors to settle in the closed position
• Thermal Protection. In the event of solenoid overheating, a thermal fuse will operate, eliminating any fire risk
