What are wafer locks used for

Surely, most of us are familiar with everyday locks such as deadbolts, keypad locks, and padlocks. But there’s a whole world of lesser-known lock types out there that many people aren’t aware of. One of these less common locks is the wafer lock. This lock was created in the 19th century and received its patent at the start of the 20th century. It bears some resemblance to the pin-tumbler lock but differs significantly in design. Unlike pin-tumbler locks, which often involve multiple components, a wafer lock is made from a single piece. These locks are typically found in file cabinets, drawers, and even some vehicles. Let’s dive deeper into how they work and their security features. Wafer locks are composed of a cylinder, springs, and a cam that controls the locking mechanism. They also include a plug that rotates when the correct key is inserted and wafers, which are small, flat metal pieces serving as the heart of the lock. Each wafer lock requires a specific key that matches its unique wafer configuration. There are two main types of wafer locks: single-bitted and double-bitted. Single-bitted locks feature wafers on just one side, while double-bitted locks have wafers on both sides. This latter design makes picking the lock more challenging since you’d need to align with two sets of wafers instead of one. Now, let’s talk about how these locks function. Inside the lock, the cylinder contains a plug surrounded by wafers that block its movement. When the right key is inserted, it pushes the wafers upward, allowing the plug to rotate freely. This rotation enables you to turn the key, triggering the unlocking mechanism. However, using the wrong key will leave the wafers misaligned due to the force of the springs holding them in place. This could result in damage to the lock, requiring professional locksmith assistance to fix or replace it. When it comes to security, wafer locks are generally considered less robust compared to other types like pin-tumbler locks. Their relatively simple design offers fewer barriers for potential intruders. With only one set of wafers, the lock presents a wider opening, making it easier to pick. For this reason, wafer locks are typically not recommended for securing external doors. Instead, they’re better suited for protecting items inside drawers, cabinets, or cars where the risk of theft is lower. In vehicles, these locks are often paired with additional security features, providing adequate protection. In summary, selecting the right lock depends on your specific needs. If you’re looking for a cost-effective solution to secure contents within drawers or filing cabinets, a wafer lock could be an ideal choice. They’re straightforward to install and replace if needed.
