How does the lock work?
With the supplied door followers, all glass panels are linked together. When you slide one panel, the other panels automatically move along with it. Separate door followers can easily be ordered individually.
When the glass sliding doors are fully closed, this connection allows you to lock the entire sliding door system with a single lock.
As standard, one sliding door system can be operated from the outside using a key. The remaining sliding door systems can easily be secured from the inside with the sliding lock.
Lock multiple sliding door systems with one key
One sliding door system comes with a keyed lock as standard, allowing you to open and close it from the outside. Secure the remaining sliding door systems from the inside with the supplied sliding lock.
Would you like to lock more than one sliding door system from the outside? Order a cylinder set. All cylinders within a set operate with the same key.
The keys supplied with the cylinders cannot be duplicated by third parties. The manufacturer does not supply replacement or duplicate keys either. We therefore recommend storing the keys in a safe place.
- 2 sliding door systems: set of 2 cylinders
- 3 sliding door systems: set of 3 cylinders
- 4 sliding door systems: set of 4 cylinders

Calculate your price
Choose your product, your veranda type and the side(s) you want to fit with a lock. The number of sliding door systems you want to lock from the outside with a key determines how many cylinders you need.
