As one of the more highly utilized recessed hinges, a butt hinge is typically manufactured to be about 6 inches or shorter. They have multiple uses and are installed for a variety of different applications. Generally, a butt hinge is used to mount and operate doors on commercial properties and residential homes.
A butt hinge is usually comprised of two leaves that match. One is usually attached to a fixed component (such as a door jamb) and the other is attached to a moving component (such as a door). In the closed position, the butt hinge leaves will remain flush with each other where only the curled barrel, often referred to as the knuckle, is exposed.
They are manufactured in a variety of finishes and materials including aluminum, galvanized steel, galvanealed, hot & cold steel, and stainless steel. There are specific applications for a butt hinge in a variety of industries. Many are constructed from stainless steel materials to be able to withstand many types of harsh environmental conditions. Butt hinges can be viewed in many applications including on fire doors, box lids, cabinets, interior & exterior doors, etc.
