A Suffolk latch, also known as a thumb latch, is a traditional and straightforward type of latch commonly used for gates, external doors, and even internal cottage-style doors.

Design and Functionality:
- The Suffolk latch consists of two main components:
  - Latch Bar: This is a horizontal bar that drops down to secure the door or gate.
  - Latch Handle (Keeper): The handle allows the user to lift the latch bar and open the door.
- When the latch handle is lifted, the latch bar disengages, allowing the door to swing freely.
- It’s a simple yet effective mechanism that has been used for centuries.
Use Cases:
- Gates: Suffolk latches are commonly found on garden gates, barn doors, and other outdoor structures.
- External Doors: They can also be used on external doors, especially in rustic or period-style homes.
- Internal Doors: For internal doors, especially those with a ledge-and-brace design, Suffolk latches add a charming touch.
Security Considerations:
- Since the Suffolk latch is a latch-only mechanism, it’s essential to pair it with an additional secure lock if used on an external door.
- For security purposes, consider combining it with a deadbolt or other locking system
