A Wafer Tumbler Lock is a type of locking mechanism commonly used in various applications, such as doors and cabinets. It operates using flat, wafer-shaped tumblers that align with a specific key. When the correct key is inserted, the tumblers move into the correct position, allowing the lock to turn and open. These locks are often favored for their simplicity and cost-effectiveness. They are less secure than other locking systems, like pin tumbler locks, but are still widely used in situations where moderate security is sufficient. Their design makes them easy to manufacture and install.
