All DOM mechanical cylinders can be adapted in length to the different door thicknesses.
- The standard length of a locking cylinder is 60 mm (30/30 mm), depending on the system.
- Extensions are possible in steps of 5 mm.
- There is no length limit.
With the modular system, the cylinder body is not made up of one piece, but instead of two halves that are connected to each other with a steel bar. The modular design allows a subsequent extension of the cylinder without having to buy a new lock cylinder.
