Hi

When i try to replace the old door level and i face some problem. The default thickness for the new Isabella Entrance Lever was 55mm and my door is 35mm. How to remove the hander and cover plate to adjust into 35mm.
Please assist as I can not find any information from the website and the manual attach.
The Isabella Entrance Lever is suitable for door thickness 35 mm to 55mm .
