Masterpiece Top Auto Flush Bolt And Bottom Fire Bolt - Z840/8bfb Family Size [G2XLA9Yy]

The Z840/8BFB is a cutting-edge security solution designed for doors in need of enhanced fire protection and durability. This comprehensive kit combines the Top Auto Flush Bolt and the Bottom Fire Bolt, offering a seamless and robust locking system. Engineered for both metal and timber doors, the Z840/8BFB ensures that your building remains secure and compliant with fire safety regulations.

Key Features and Specifications

The ZBFB Bottom Fire Bolt is a standout feature of this kit. It eliminates the need for a separate bottom automatic flush bolt and dust proof strike, simplifying the installation process. The ZBFB is horizontally installed in the inactive door, with a mating hole in the edge of the active door. Its strategic placement, usually within 102-152mm of the door's bottom, ensures optimal performance. When subjected to temperatures of 230°F (110°C), the ZBFB projects a spring-loaded bolt, locking the leaves together. This product is designed without intumescent materials, providing a reliable and straightforward solution for fire-rated doors.

Practical Uses and Benefits

The Z840/8BFB is fire rated for 3 hours on metal doors and 20 minutes on timber doors, making it an ideal choice for buildings that prioritize fire safety. The kit can be purchased separately or as part of a comprehensive security system, which includes the 842, 942, and 862/962 single automatic flush bolts for the top of the door. This versatility allows you to customize your security needs while ensuring compliance with industry standards. The Z840/8BFB not only enhances the security of your building but also adds an extra layer of protection against unauthorized access and potential fire hazards.
  • Fire-rated performance: Up to 3 hours on metal doors and 20 minutes on timber doors.
  • Easy installation: Horizontal installation in the inactive door for quick and hassle-free setup.
