How does a Cam Lock Work?

1. A cam lock is a common type of lock seen on lockers. Inside the lock is a metal plate known as a cam, which is attached to the core of the locking device.

2. When the cam is turned one way, it rotates as the key is turned. The cam rotates between 90 to 180 degrees, locking and unlocking the locker door.

3. Cam locks can also be opened with a master key, making them one of the most convenient types of lock to deal with in the case of an emergency, like someone losing their key.
