=> Choose the lock attachment according to the slat:



- An 8 mm slat corresponds to a slat height of 30 to 45 mm.
- A 14 mm slat corresponds to a slat height of 50 to 60 mm.

=> Usage recommendations:

- Locks and attachments fixed on the shaft must always be positioned at the ends closest to the guides (maximum 20 cm).
- It is recommended to provide at least two curtain locks: one lock every 80 cm.
- Lock attachments are recommended for crank and motor operations.

In the case of motor operation: the use of motors with automatic limit switches is recommended.
Why? If the limit switches are poorly adjusted and depending on the motor power, it could cause the locks to break.
