Sliding doors require unique lock systems due to their sliding motion. Here are some common types of sliding door locks:
1. Latch Locks: The most common type, these usually come with the sliding door and are a simple latch that locks the door from the inside. They are easy to use but offer limited security.
2. Hook Locks: As the name indicates, these locks consist of a hook-shaped device that juts out to lock the door into the frame. They are much more secure than latch locks and can be keyed for extra protection.
3. Deadbolt Locks: Deadbolt locks offer perhaps the highest level of security. The deadbolt extends from the door into the frame. Once the deadbolt is extended, the door cannot be opened until the deadbolt is retracted.
4. Key Locks: Key locks can be installed for additional security. They are usually installed either in the handle or separately on the frame. Key locks for sliding doors typically use the same kind of lock and key as traditional doors.
5. Bar Locks: Installed on the inside of the door, these locks consist of a sturdy bar that extends across the door onto the frame. When the bar is extended, the door can’t be opened from the outside.
6. Smart Locks: These are the newest type of lock and offer a variety of locking and unlocking methods, like keycode, fingerprint, or smartphone control. Some can even connect to home automation systems for added convenience.
When choosing a lock type, be sure to consider both the security requirements and the convenience of operation.
