we have a bit of an issue which has caught us out a few times as when we use a standard cupboard from our library and change the hinging say from LH to top hung the slack follows the door and not stay with the cabinet faces (top, bottom, LH or RH)
attached is a wall unit for reference where top, LH & RH slack is 1.5mm while bottom is 0mm.
when change the fitting side to top the slack is rotated clockwise to follow the front?? with LH being 0mm and bottom 1.5mm
