Cam locks: the most common method of locking a cabinet
Cam locks are the most common method of locking a cabinet. They are a type of wafer lock that uses a rotating metal plate, or 'cam', to secure the locking mechanism. When the key is inserted and turned, the cam rotates, either dropping to the side to lock the cabinet or rising vertically to unlock it.
Cam locks come in a variety of sizes and designs, with different cylinder types that impact how the lock is opened. They are available with single- or double-throw lock mechanisms and can be configured for one or two key pulls within a 90-degree rotation. The cam size and type of latch will depend on the specific cabinet and the level of security required. For example, an industrial manufacturing cabinet might use an easy-to-open quarter-turn cam latch, while a high-security application would require a pin tumbler cam lock.
When installing cam locks, it's important to consider the depth of the door and the type of hole required. Some cam locks require a rectangular hole to be cut or punched into the door, while others use a standard rounded hole. The housing of the lock must fit the application and offer the desired functionality.
Cam locks have been around for over 130 years, with early brass cabinet locks equipped with pin tumbler locking mechanisms appearing in the late 19th century. Today, cam locks are continuously being developed and refined to provide locking solutions for residences, commercial spaces, and institutional facilities. They are a versatile and secure option for locking cabinets and enclosures.
