Concealed or European Hinges
Also called 35mm hinges for the diameter of the mortise hole in the cabinet door, European hinges are fully concealed behind the cabinet door, so they’re not visible when the door is closed. Boring the hole in the door for the hinge can be a challenge, but if your doors already have it, these hinges are a cinch to install. They’re self-closing and usually easily adjustable.
Uses: Available for both frameless and face frame cabinets, and most standard door overlays and insets.
