Tips while purchasing door knobs First and most primary thing to remember while purchasing doorknobs for your house is that, you need to know which door you wish to use it for. This is important because stores provide different materials and styles of doorknobs for different doors of the house. For example, if your requirement is for the front door then you should be looking out for a keyed door knob. If bathroom doors is what you are concerned about then, privacy ones (the locking/unlocking) ones should be the choice. The other types of doorknobs include, passageway ones used for the halls that do not have a built-in lock system, and the artificial, or the dummy ones. Choosing the right doorknob is necessary as privacy and safety are a concern of every household. Also, it is important to keep the theme of the room in mind while choosing the door knobs. If the theme is royal or simply old age then, a lovely Egyptian mask doorknob look classy. Antique knobs also work as a contrast to the modern interiors of the house. This makes them look attractive and catchy.
