What types of bolt and latch locks are there?

There are several different types of bolt and latch locks, which can be used in different situations and for different security requirements.

First, there are mortise locks. These can be fitted with either bolts or latches and are usually installed in interior doors. Mortise locks are easy to install and remove and provide a solid basis for protection against unauthorized access.

• Cylinder locks: These are a type of mortise lock in which the key turns a cylinder to open or close the locking mechanism.
• Bit key locks: These are another type of mortise lock that are generally less secure but more cost-effective. They are well suited for rooms where a lower level of security is sufficient.

Second, there are surface-mounted locks or hasps. In these, the bolt or latch is mounted externally on the door or gate rather than recessed into it. They are often used for garden gates or sheds, as they are more robust and weather-resistant.

When choosing the right lock, users should always consider the specific requirements for security and ease of use.
