Cylindrical locks are the most common lock type available typically used in a single or double bore application. These locks are installed into a hole, or bore, that is cut in the face of the door while a latch bolt is installed into a bore on the edge of the door, commonly referred to as the edge prep of the door. This type of lock has a quick and easy installation process.
