Hinges Hinges also come in a variety of styles today. They must be matched to the type of cabinet door they are being used on. There are exposed hinges and concealed hinges. The exposed hinges obviously can be seen but like backplates they can add unique style and personality in combination with your knob and pull choices. They can be further classified into full surface mounted hinges for flush mounted doors, semi-concealed hinges for lipped doors, and pivot , butt hinges and semi-concealed hinges for flush overlay doors. Further to the above considerations, you can choose self-closing hinges. These are offered in many types as replacements for standard non self-closing hinges.
