tick Slave

The Roto H609 is a technical slave unit door lock designed for the secondary leaf of double or French door sets. It serves as the primary locking mechanism for the non-active door, ensuring a secure closure and alignment with the master door leaf.

Featuring a 35mm backset and 92mm centres, this unit is built to industry-standard dimensions, making it suitable for both replacement projects and new door assemblies. It is specifically designed to be used with shootbolts, which provide additional security by anchoring the slave leaf into the head and sill of the door frame.

The lock operates via a single spindle and is compatible with standard euro cylinder locks. It is commonly used in PVCu and timber door systems where a robust, synchronised locking solution is required for twin-door configurations.

FAQs

The Roto H609 slave door lock is designed specifically for the inactive leaf of double door sets. It acts as the central gearbox for the secondary door, allowing it to be secured or released once the primary door is opened.

No, this unit is the central gearbox only. For a complete multi-point security setup, it must be used in conjunction with additional top and bottom shootbolts that secure the secondary leaf to the frame.

To ensure this lock fits your door preparation, please note the following technical specifications:

  • 35mm backset
  • 92mm centres for handle and cylinder alignment
  • 16mm faceplate designed for standard grooves

Yes, because this lock uses a standard 92mm centre and accommodates standard Euro profile cylinders, it is compatible with a wide range of standard door handles and locking cylinders.
