Door Knob. Tuesday , December 05th , 2017 - 05:08:21 AM
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.
To keep the original look and finish, porcelain door knobs must be dusted regularly. They can be cleaned using warm soapy water. Try to avoid abrasive cleaning materials, as they may damage the porcelain. You can buy porcelain door knobs from any of the door hardware manufacturers. Most of the models come with a limited lifetime mechanical warranty. For convenience, rosettes, spindles, and other mounting accessories are provided with the porcelain door knobs. The price of door knobs varies from model to model. They usually range from $10 and $100 per knob. Great discounts are available when purchased online.
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.
