Inside length and outside length:
Measuring a cylinder
The inside length and outside length of your door determines what length the cylinder needs to have to have an exact fit.
The cylinder should neither protrude (safety!) nor be too short (mounting!). The lengths are standardized and have the following typical lengths in 5mm intervals: 30, 35, 40, 45, 50, 55, and 60. We offer the SOREX SMART digital cylinders in total lengths (inside + outside length) of 60 – 100mm.
Inside length: Measure from the middle of the lock to the inside edge of the door. (Diagram A)
Outside length: Measure from the middle of the lock to the outer edge of the door. (Diagram B)
