Single Acting: Single acting hinges swing in one direction.

Plain Bearing: Plain bearing is the simplest type of bearing. They are a good low cost option for lightweight doors.
Ball Bearing: Ball bearing hinges have ball bearings to act as a buffer between the knuckles. They tend to be quieter and more durable than plain bearing hinges. They are recommended for heavy doors and doors fitted with closers.
Roller Bearing: Roller bearings are able to support very heavy loads. Many of our heavy duty gate hinges are equipped with roller bearings.

Face Frame: Face frame cabinets have a “frame” that attaches to the front of the cabinet. The face frame gives the cabinet box extra strength while adding dimension to the door fronts. Face frame cabinets are commonly made by American cabinet manufactures.
Frameless: Frameless cabinets do not have a face-frame, and instead rely on thicker side panels for strength. Frameless cabinets are very common in Europe, but have steadily been making their way into America, as they lend themselves well to contemporary and modern designs.

The center to center is the distance from the center of one screw hole to another. Most manufacturers use this measurement to identify the size of the pull.
