The new System One measures only 18 mm in height, making it much thinner than the previous One. It is available in two versions: the classic System One 70 mm and the System One 40 mm.

System One 70 mm has a rotation point starting from 70 mm from the edge of the door, up to a central position. System One 40 mm can be paired with the 40 mm top pivot and has a fixed rotation point at 40 mm from the edge of the door. Internally, these products are identical.
