Mortice Door Knob Fitting
A Mortice door knob is a popular type of handle used for opening and closing a door. In its simplest form, a doorknob provides only a place to grab so that the door may be pulled toward oneself. On most modern doors, however, doorknobs can be turned to operate a latching mechanism, which normally holds the door closed. A doorknob may also have a lock built in, though in some cases it is beneficial for the lock to be separate.
Most household Mortice door knobs use a simple mechanism with a screw-style axle (called a spindle) that has at least one flat side, which is passed through the door latch, leaving some length exposed on each side of the door to which the knobs are attached. Knobs are attached on both sides by screwing them directly onto the spindle, and then securing one or more retaining screws (set screws) through the knob perpendicular to the flat of the spindle. Door knobs that lose traction can frequently be repaired by replacing or adjusting the set screw, which prevents them from slipping on the spindle.
The location of the door knob on the door may vary between a few centimeters away from the edge of the door to the exact center of the door, depending on local culture, decorative style or owner preference. The distance from the edge of the door to the center of the doorknob is called the backset.
