A latch lock is normally used to secure a surface (door) to another surface (frame) this can be typically done with a padlock that engages once the latch is closed, the part of the lock which moves is the metal panel (i.e. latch) and also the fixed part of the mechanism is known as the keeper or striking plate. A latch lock ranges entirely in its form of complexity and exactly how secure it is, the following are types of latch locks;
• Dead Lock Type
This sort of lock is utilized usually on office and home exterior doors as the spring latch will engage the locking mechanism when the door is shut which means a handle access isn’t likely from the outside with no key without having to fully lock the door from the inside.
• Spring-loaded Bolt
By far the most common type is a spring-loaded bolt or metal bar, which is engaged in the event the door is shut. This is done with a spring-loaded mechanism, to release the latch, a thumb point is utilized to raise the latch and disengage the door from the lock.

It’s just about the most basic as well as a somewhat low security type of latch lock, the mechanism features a bar which happens to be secured with fixing plates and slide across in front of the door opening right into another fixing plate which has a small handle to function. A very primitive version of this lock is a wooden beam that’s put into front of the door fixed on with angled fixing plates blocking entry to the inside.
• Cabin Hook Type
Usually used in combination with padlocks, this one of many commonly used latch lock mechanism. A Latch is utilized which then hooks over a staple, the staple is attached to a fixing plate where the screws are hidden once the latch is in locking position and a padlock is added to prevent having access to the door. An alternative type of cabin hook is a staple connected small metal hook, in which suits in to an adjacent staple on the opposite surface which means entry from the exterior is tough however, not impossible without having the hook disengaged.
• Cam Type
