The bolt locking system

Discover innovative bolt locking systems from BKS that combine security, comfort and flexibility for doors in public buildings, hospitals, airports and more. 

Brief and clear 

What is a bolt locking system?

A mechanical or motorized lock that securely and reliably locks the door leaves using two locking rods. These bolts engage in strike plates and mechanically secure the inactive leaf of a double-leaf door at the top and bottom. This significantly increases resistance to forced entry and the stability of the door. Additionally, the bolt locking system, which is mounted on the inactive leaf side, allows the active leaf to be opened mechanically or motorized at any time in an emergency situation.

Function & benefits of a bolt locking system

  • Maximum security: The bolt locking system mechanically secures the inactive leaf of a double-leaf door at the top and bottom and is optionally available with monitoring contacts. This ensures functional reliability even for extra-high doors.

  • Comfort and fast operation: There are both manual and motorized bolt locking systems. Both offer comfortable and fast operation. Motorized locks feature a powerful motor for particularly rapid unlocking – ensuring smooth access and efficient operation in high-traffic areas.
  • Cost efficiency and easy installation: Manual bolt locking systems do not require a power supply on the inactive leaf, eliminating the need for complex wiring, reducing costs and installation time, and allowing for easy retrofitting.
  • Flexibility for diverse requirements: The bolt locking system can be installed in double-leaf doors that can also be operated as single-leaf doors – ideal for variable usage scenarios.

Where are bolt locking systems used?

Bolt locking systems are mainly found where double-leaf doors are used:

  • In public buildings: Hospitals, airports and authorities benefit from the secure, fast locking solutions of the bolt locking system, which combine accessibility with high protection.

  • For escape and rescue routes: Compliance with EN 179 and EN 1125 standards ensures safe use in emergencies while providing comfort for daily operation.
