Is it possible to install profile cylinders of different lengths?

Yes, it is absolutely possible to install profile cylinders with different lengths in your door. The key to a successful installation lies in measuring the required cylinder length correctly.

To determine the correct length, you need to measure from the center of the lock (where the key turns) to the edge of the door on both sides. The total length of the cylinder will be the sum of these two measurements. This dimension can vary depending on the thickness of the door, the type of fitting, or the presence of any overhangs.

• The first length specification (A) measures from the center of the profile cylinder to the end of the cylinder on the key side or thumbturn side.
• The second length specification (B) shows the distance from the center of the cylinder to the end on the other side.

The usual profile cylinder dimensions are: 30/30, 30/40, 30/45, 35/35, 40/40, etc. It is important to note that different doors may require different profile cylinder lengths. Therefore, it is always advisable to measure before buying a new profile cylinder!
