Requirements:

The FLEX COMFORT Cylinder is suitable for the following door dimensions:

• Door thickness: 32mm~120mm (variable adjustable Outside 35–63mm / Inside 35–63mm)
• We recommend a minimum distance between the centre of your door lock and the door frame (backset) of 36mm so that the cylinder does not brush against the frame.

Instructions for measuring the required dimensions can be found here.

Operation and set-up of the SOREX SmartLock App required for operation of the cylinder can be found here.
