Wafer locks are a type of locking mechanism commonly used in various applications, including doors and cabinets. They consist of a cylinder that contains a series of flat, wafer-shaped tumblers. When the correct key is inserted, the tumblers align, allowing the lock to turn and open. These locks are known for their simplicity and cost-effectiveness. However, they can be less secure than other types of locks, such as pin tumbler locks, because they are easier to pick or bypass. Despite this, wafer locks remain popular for low-security needs due to their ease of installation and use.
