Most door knob manufacturers are also wholesale suppliers and exporters. The commonly used materials for making door knobs are brass, iron, wood, wire, ceramic, stainless steel and aluminum. Door knob is a handle used for opening and closing a door. Door knobs are often sold as complete locksets. Porcelain door knob/rosette assemblies are offered for both sides of the door. Passage/privacy sets consists of a latch, faceplate and strikeplate.
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.
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.
Although there are a number of glass knob manufacturers that have come out with several replicas of the Victorian glass door knobs, they haven`t been able to match the quality, precision, and detail of antique glass knobs. Although brass, chrome, and steel knobs look good on doors they tend to lose their sheen and color due to the weather conditions. Moreover the constant touch of sweaty or wet hands on these door knobs can make them look drab. Antique glass door knobs are durable and are prone to different weather conditions.
If you think about it, the door knob began the whole movement towards security and safety in the home. Before the door knob, doors would just push open when someone wanted to get inside or go out. Then along came the door knob. It was a great way to keep a door from opening accidentally. A door knob also offered a side benefit of keeping the elements out of the house. Imagine how things would be in a storm without a door knob. Rain and wind would rush in every time.
