Klevio Tip: Nightlatch vs. Deadlatch

To provide the best digital access solution possible, the Klevio operations team need to consider different types of locks. In our newest Support video, our installer Farhan explains the difference between a nightlatch & a deadlatch.

Nightlatches in general all have a triangular bolt that springs into a keep installed on your door frame when your door is shut. That way, the door is secured so that it cannot simply swing open.

Regular nightlatches have a security issue

The difference between a nightlatch & a deadlatch lies in a security flaw inherent to regular nightlatches.

The bolt on a regular nightlatch is itself not secure when the door is closed. If someone managed to slip an object like a card between your door frame & lock, they could potentially force the bolt back into the nightlatch to open the door.

Deadlatches secure the bolt when the door is closed, making them less vulnerable to attack

Deadlatches (also called “deadlatching nightlatches”) have an additional snib under the bolt that resolves this security issue.

When the door is open, the snib is free and the bolt can be pushed back into the latch, as one would expect with normal nightlatches.

But, when the door is closed, the snib gets depressed, which triggers a mechanism that secures the bolt above it – effectively deadbolting & securing the nightlatch so it cannot be forced open.

This is why deadlatching nightlatches are generally more secure than regular nightlatches.

Check out our video below where our installer Farhan explains the difference between a nightlatch & a deadlatch with two practical examples:
