What is a Door Latch?
A door latch is a type of mechanical fastener that is used to join two (or more) objects or surfaces together while allowing for the regular or eventual separation of the objects or surfaces. In other words, the door latch is the little piece of hardware that helps keep a door shut so it doesn't open by itself. A latch typically engages another piece of hardware on the other mounting surface. Then, when you want to open a door, the latch must be moved out of the way so it can open.
You may think that all you would need to do if you are in need of a latch is simply order one and then it would be boxed up right away and shipped to your front door, but you would be wrong. It's a little more complicated, because there are several kinds of latches. They function basically the same, but there are small differences, so let's go over some of the basic door latch types that we are familiar with.
Standard Latch

Here is your standard latch. It's the basic one you would use on a passage or privacy door or the interior doors of your home. Each latch will come with a rectangular shaped face plate with either round corners or square corners. The face plates require chiseling out the wood on the side of the door (where the plunger part of the latch comes in and out), that way the plate is flush and screw mounted to the door.
