Lock cylinder by Abus with dimensions 45-45mm. The total length of the lock cylinder consists of two dimensions. The first starts from one edge to the center of the cylinder, where the screw is placed, while the second concerns the distance from the center to the other edge of the cylinder. Usually, the hole for the screw is not exactly in the middle of the cylinder, and the part with the smaller dimension is placed on the outside of the door. In this case, the total length of the cylinder is 90mm, with the part from the screw hole to the outside of the door being 45mm and the part from the hole to the inside of the door being 45mm.
