Door alignment

The DIN direction of the door alignment is also important for the selection of the lock. A distinction is made here between DIN right and DIN left.
If the door hinges are on the left-hand side when observer looks at the closed door, this is a door with a DIN left door, if the door hinges are on the right side, this is a DIN right door.
