A cam lock is a type of locking mechanism commonly used in cabinets, lockers, and furniture. It consists of a cylindrical body that houses a rotating cam, which secures the door or drawer when turned. When the key is inserted and turned, the cam rotates, either locking or unlocking the mechanism. These locks are popular due to their simplicity and effectiveness. They are often made from durable materials like metal or plastic, making them suitable for various applications. Cam locks can be found in many settings, including homes, offices, and schools, providing security for personal belongings and important items.
