What is a multi-point lock?

As the name suggests, a multi-point locking system is a lock that engages multiple locking points along the door frame when the door is closed. This creates a more robust barrier against unwelcome guests.

A multi-point locking system typically consists of a central locking mechanism and multiple additional locking points distributed vertically along the edge of the door. When the door handle is turned, or the key is turned in the lock cylinder, the central mechanism engages the additional locking points into corresponding strikes or keepers installed in the door frame.

These locking points can include bolts, hooks, or rollers that extend and secure the door at multiple locations. When you unlock the door, a single action, such as turning the key or operating the handle, will retract all the locking points simultaneously, allowing the door to open smoothly.

All of that information might sound too technical, so let’s look at the ups and downs of this lock.
