A latch lock is commonly used to protect a surface (door) to a different surface (frame) this can be typically done with a padlock that engages once the latch has been shut down, the part of the lock that moves is the metal panel (i.e. latch) and the fixed area of the mechanism is known as the keeper or striking plate. A latch lock can vary fully in its kind of complexity and the way secure it is, the following are types of latch locks;
Spring Latch Type. This lock is probably the most affordable and easy enough for pretty much anyone to install. Meanwhile, it is the most weak and gives the smallest amount of security to the homeowners. This device locks the doorknob and prevents release of the latch which happens to be spring-loaded in the door frame. A key is commonly used to release the latch and let the user to turn the knob. However, a spring latch lock does has its cons. A device other than the key, in the hand of somebody who knows what they’re doing, may be used to release the bolt and permit access.
Dead Lock Type. This type of lock is used typically on office and residential exterior doors considering that the spring latch will engage the locking mechanism when the door is closed which means that a handle access isn’t likely from the outside without a key without needing to fully lock the door from inside.
Cross Bar Type. This is probably the most simple and also a fairly minimal security type of latch lock, the mechanism includes 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 operate. A really primitive type of this lock is a wooden beam that’s positioned in front of the door fixed on with angled fixing plates controlling ability to access the interior.
Cabin Hook Type. Usually used in combination with padlocks, this one of many frequently used latch lock mechanism. A Latch is used which then hooks over a staple, the staple is attached with a fixing plate where the screws are hidden once the latch is in locking position and also a padlock is put into prevent entry to the door. An alternative type of cabin hook is a staple connected small metal hook, that suits in to an adjacent staple on the opposite surface which means that entry from the exterior is difficult however, not impossible without having the hook disengaged.
Cam Type. Such type of lock is utilized on lockers in places for example schools, universities and colleges. This is because students could secure their lockers if you use a padlock in some cases a small combination padlock ensuring that the person/s will not lose any keys. The cam type of this is extremely similar in mechanism to the cabin hook latch lock in in which a padlock is positioned over the latch cam lock when in the locked position to secure the device.
