Measure your suitable cylinder easily
Before you order your Yale ENTR, you should measure the cylinder size you need. The outside measurement A and the inside measurement B are required (see graphic). A is the length from the end of your door's exterior to the faceplate screw (this is the screw in the middle of your door). B is the length from the faceplate screw to the end of the inside of your door. (length A / length B) in mm corresponds to the required cylinder size (e. g. 30 / 45). Important: Your cylinder should not protrude more than 3mm from the outside. We are always there for you if you have any questions.
