A strap hinge is a type of hinge that has two long flaps which are generally triangular in shape; one strap is screwed into the surface of a moving part, such as a door or gate, and the other into the adjacent stationary surface. The long flaps of the strap hinges provide added stability for the door or gate. Strap hinges are typically used for door hinges (such as barn doors, shed doors, and garage doors), gate hinges, and cabinet hinges, and are meant to be seen.
