Concealed hinges are not visible when doors are closed. Sugatsune has two types of hinges that are hidden when door are closed. One is concealed hinges, and the other is European hinges. These concealed hinges are used as connections between doors and frames. They not only keep the outward appearance clean but also have security benefits. For instance, it is hard to break the hinges when closed. Some of them are available with "3 way adjustability" that makes it easier to install doors.
