What do you mean by 4 drillings? Four on one side? Or four in total? The latter would apply to my door, two drillings on each side...
Four in total, two on each side. The other doors only have the drillings on one side because they can be mounted with a left or right hinge by rotating them 180°. The 125 model has the four drillings because the holes at the top and bottom do not have the same distance from the edge (if I remember correctly). Measure it yourself.
