DOORBANDS
Door hinges serve as a connecting piece between the door leaf and the frame. They are there to enable the door to be opened and closed by turning.
A door hinge consists of a hinge upper part, which is attached to the door leaf, a leaf lower part, which is attached to the door frame, and a pivot bolt, which connects both parts with each other. The pivot bolt allows the door to rotate.
Door hinges are found on the opposite side of the lock and strike plate. They offer the possibility of still aligning a door leaf to a limited extent in all three dimensions (side, height, pressure) when it is hung.

In the simplest case, the door viewer consists of a hole placed at eye level with a flap to close it. Modern door viewers have a wide-angle lens that greatly increases the angle of detection, allowing the occupant to see more of the area in front of the door.
