can it be that there is a serious flaw in the way how the install guide in the Nuki app calculates the dimension for the universal cylinder? When I follow the measurement guide to the letter I end up with the cylinder being much shorter than the old one that I removed from the door. It doesn’t fit on either side. The inner side is too short, and the outer side is way too short. According to the guide I should have removed two of the pre-mounted extensions on the inner side, and no extension necessary on the outer side. To make it fit actually, I had to rearange the extensions on the inner side, and add the 40mm extension for the outer side.
So I was able to install the cylinder finally, but the guide in the app was entirely useless.
Hello!
the calculations for the cylinder installation were tested thoroughly on various doors and various cylinder lengths and it was adapted if needed.
if the steps, which are also available on the Ultra mounting installation page, where followed and entered correctly, the cylinder should fit pretty well for the Ultra installation.
if you came across that it doesn’t fit, it would be the best for us if you could provide feedback containing:
the measured values from the old cylinder
the suggested values for the new cylinder
the used values for the new cylinder
