The cylinders are available in different lengths. The cylinder starts at 30 / 30mm by default and can be extended by 5mm each time.

How do you measure your cylinder? It is best to measure from the center of the screw, on the side of the cylinder, to each end. Left and right does matter with a knob cylinder because you cannot turn them around.

Therefore, pay attention to what the inside and what the outside is. The first number is the outside (A) and the second number is the inside (B). Example: if you choose a cylinder of 30/40 (A / B) it is from the screw in the middle 30mm to the outside (A) and 40mm to the inside (knob side, B)
