Cylindrical Lockset

Definition and meaning of Cylindrical Lockset in real estate.

A cylindrical lockset is a common door lock mechanism that fits into a large hole bored through the face of a door stile and is secured by a latch bolt mechanism. This design is widely used for both interior and exterior doors in residential and light commercial buildings.

In more detail

Cylindrical locksets are popular because they are relatively easy to install and replace. The mechanism features a cylindrical chassis that houses the locking components, which simplifies the door preparation process. A small latch bolt extends from the edge of the door into the frame to secure it.

While they are suitable for standard security needs, exterior doors often pair a cylindrical lockset with an independent deadbolt to provide extra protection against forced entry.
