What Is A Door Hinge
A door hinge is a piece of hardware that attaches to the door and the doorframe, controlling how the door opens. Most of the time, there are two or three-door hinges that help it operate. In the bottom, top, and center.
Butt Hinge
If you don’t like the name butt hinge, you can call this type of hinge a mortise hinge. They are very common, inexpensive, and simple. They are generally symmetrical and consist of two panels, one on each side.
One panel attached to the door and the other attaches to the door jamb. Oftentimes, there is a pin that holds the two pieces together to make it easy to install the door hinge without having to hold the door up the whole time.
