European 35mm Cup, 1/2" Overlay (1/4" and 3/4" Overlay Available), Concealed Cabinet Hinges. Our European hinges work very well on most face frame and frameless applications. Unlike most hinges found in big box stores, our hinges come with 8mm plastic grommets on the screws to provide a much stronger hold on your cabinet doors. If you are purchasing our hinges, please select "Cup" under dado type. If you are using some other brand of cup hinge, you may need to select "Cup(no side holes)" for your dado type.
