Will it fit on my door?
Therefore, take the minimum and maximum door thickness of your product from the product page. For lock cylinders, please also pay attention to the external and internal length.
The minimum and maximum allowed door thickness of your product can be found on the respective product page. In case of lock cylinders, the external and internal length must also be taken into account (A & B).
Any door rosettes or fittings that are to remain after installation of the product must be added to your measured lengths! In this case, add dimension C to dimension A and/or B.
If the cylinder is "too long" for your dimensions and protrudes too far from the door, you can easily compensate the excess length with a corresponding door rose. You can get these in any building supply store.
Door - Backset
Please ensure that the distance between the edge of the door leaf (forend front edge) and the center of the door lock is large enough (backset).
This is especially important because otherwise our products (door fitting, cylinder, etc.) might touch the door frame when opening and closing. Please refer to the respective product page for the minimum backset
For our door handles you need two 8mm holes in the door to the left and right of the square. These holes are needed for the fixing screws of the door handle.
The distance between the center of these two drillings is 38mm. These are standard holes and are already drilled on almost all doors and lock cases.
