A cylinder lock (100) comprising first and second housing sides (104, 106), an actuator (120) which is positioned in a space (116) between the first and second housing sides (104, 106), and a connecting portion (200) which extends completely across the space (116) and connects the first and second housing sides (104, 106), and wherein the actuator (120) is rotatable about the connecting portion (200) in order to cause operation of locking means. The connecting portion (200) gives the cylinder lock (100) increased strength.

A lock system includes a cover, a lock assembly, and a baffle. The cover includes a first aperture defining a first cross-sectional dimension. The lock assembly includes a lock mechanism defining a second cross-sectional dimension. The baffle includes a base and at least one leg. The base includes a second aperture defining a third cross-sectional dimension smaller than the first cross-sectional dimension and larger than the second cross-sectional dimension. In an assembled configuration, the base engages the cover, the at least one leg engages the lock assembly, and the lock mechanism is disposed within the first aperture and the second aperture.
