There are many different ways to classify compression latches. However, the two largest categories of compression latches are locking and non-locking.
Non-Locking Compression Latches
As the name implies, non-locking compression latches have no locking mechanism. Instead, they are activated using a raised trigger. This is the simplest type of compression lever latch.
Lift-and-turn compression latches are another popular type of latch. These latches are available in both non-locking and locking configurations. When operating these latches, users must lift the latch and then rotate it to engage or disengage the gasket-sealing system.
Locking Compression Latches
The majority of locking compression latches use a key-based mechanism. Key-locking latches are a convenient means of securing exterior enclosures, such as those affixed to fire trucks or other emergency response vehicles.
Additionally, some compression latch systems feature padlocking capabilities. Attaching a padlock to a compression latch provides additional protection against theft or unauthorized access.
When choosing between locking and non-locking compression latches, consider the intended application. If the compartments will be used to store potentially valuable items, locking compression latches will usually be the better option.
