Some notes for different types of door lock fitting

Locks in interior doors

Interior doors usually fit with a mortise lock with a latch operated by the door handle or knob. Where the door is self-closing, the latch has an angled/ rounded edge and is sprung. Thus it automatically locks when you close the door.

The same lock can be available in doors that open both to the left and the right. Lockable rooms in many cases also have a locking bolt operated by the key. In contrast to the latch, a bolt does not have an angled or rounded edge and is not sprung.

Locks in exterior doors

Cylinder door lock items are the most suitable type for exterior doors. Simple mortise door lock is not secure enough for exterior doors. Cylinder locks can fit into the lock body without having to change the whole lock mechanism.

Rim door lock

If it is not possible to use a mortise door lock, you can fit a rim lock mounted on the surface of the door. This may be the case for example with a door that is less than 40 mm of thick. With a thin door like this, the recess for a mortise lock would weaken the door structure well. Rim door lock is available with a sprung latch and/or a locking bolt. They are normally only used on exterior doors.

Last of all, you can carefully bend over the lip of the strike plate with a small plastic hammer. As a result, it neatly follows the contour of the door frame. Contact HeleH Italy today if you meet any locking problems: http://heleh.it/.
