Door Knob. Friday , December 01st , 2017 - 03:29:55 AM
Once the door knob was in place, there were further advances to this invention. Soon a lock would be added to a door. That made not only a way to keep the door from accidentally opening, but also a way to intentionally keep people out. That wasn`t enough for some people, who could bust through a simple lock, so there had to be more substantial locks created. Dead bolts were added to really hold a door shut when the person inside wanted it to stay that way. At one point, there were very limited selections if you wanted a door with locks, and even more limited selections if you wanted the additional dead bolt lock that matched the door knob. But things have progressed over the years. Now you can find a door knob in almost any shape or size to do the job you need done.
A door knob is a hardware handle which is installed in a cabinet door with the use of a screw or sometimes a bolt. Compared with finger pulls and door latches, this is a better option because it is more versatile, easier to install and to use. Any color, either light or dark door knobs will definitely fit any style of door.Knobs have different ranges in terms of its size. It ranges from 1 inch to 1 ½ inch diameter which is appropriate in almost all sizes of the doors, except for the big ones. Aside from round shapes, knobs are also available in shapes like flat but the edges are round, square, or bun shape and even shaped like `T`. It can be made of metal or wood and it can just be plain or with decorations.
Interior door knobs are available in four primary styles; privacy, passage, double dummy and single dummy. Privacy and passage knobs turn and operate a latch mechanism - the difference is privacy style knobs have a push pin lock (these are generally used on bathrooms or bedrooms). Single dummy and double dummy knobs do not turn or operate a latch mechanism - a single dummy knob is one knob on the exterior side of the door while a double dummy is a knob on either side of one door. Note: Most double dummy knobs cannot be used on two separate doors.
