Before ordering your new digital door cylinder, first check whether you have installed a profile cylinder (Euro profile) in your entrance door.
We only supply digital door cylinders in Euro profile.
If you have a round cylinder (CH profile), we recommend that you contact a specialist dealer directly.
1. Determining the installed cylinder (Fig.1.)
The profile cylinder (Euro profile) has a diameter of 17 mm. Its entire front profile is visible from the outside on the door.
The round cylinder (CH profile) has a diameter of 22 mm. Only the round part of the profile is visible from the outside of the door.
2. Measuring the profile cylinder (Fig. 2.)
Do you have a profile cylinder (Euro profile)? Good! Now you only have to measure the outside and inside length of the cylinder at your front door. The removal of the door cylinder is not necessary. You only need a double meter or a ruler.
a) Measurements are taken from the center of the fastening screw.
b) If you have attached a door rosette or a fitting to the door, its width must also be included.
c) Measure the external length (A) on your door first and then the inside length (B).
d) Then order the digital profile cylinder specifying the two lengths. (e.g. 30/30 mm). It always applies first (A) and then (B).
3. Removal of the old cylinder and installation of the new digital profile cylinder
The very simple procedure can then be found in our accompanying user manual.
