What is the total length of the tail piece of key lock cylinder 82-310 ? The picture shown leads me to believe that it is 2-3/4" but I need to verify this. Is it possible to get three of these keyed alike? Thank you.

Thanks for posting! The length of the tail piece for the 82-310 Key Lock is approximately 2-1/4". Keep in mind that you can cut it down to the length you desire. Unfortunately, they cannot be keyed alike.
