When installing a new door, whether for a grand front entrance or for a small cabinet, you'll find a range of hinge styles to choose from. Besides the myriad of aesthetic options, the structural design of different hinges affects their performance. Wrap-around door hinges offer a design which ideally suits frameless cabinetry, securely "wrapping" either fully or partially around the door frame.
Full Wrap-around Hinges
In general, hinges have two basic components that are joined by a rotating pin and knuckle mechanism: one leaf attaches to the door and the other attaches to the door frame. In a wraparound hinge design, the frame-side wing has two right-angled bends, wrapping snugly around the frame to attach on its interior side. Therefore, a full wraparound hinge must be sized to match the frame. Wrap-around hinges may be mortised or non-mortised, either sitting directly on the frame or embedded into it. In general, a "wrap-around" designation refers to this design for the frame-side component only; the side of the hinge attached to the door is a traditional, unbent piece.
Partial Wrap-around Hinges
Whereas a full wraparound hinge has two bends on the frame-side leaf and attaches to the interior of a door frame, a partial wraparound hinge has only one bend and attaches to the frame's exposed edge. The partial wraparound hinge can still work with a frameless cabinet. The partial wraparound hinge offers slightly more stability than a simple surface mount or face frame hinge and slightly less than a fitted full wraparound hinge.
Wrap-around Butt Hinges
Butt hinges have a simple design, typically with two flat faces joined with either a fixed or a loose pin joint. This type of hinge is mortised, meaning that the frame-side hinge face is set into a chiselled depression in the frame. Therefore, a wraparound butt hinge fits a slightly larger door frame. In a wraparound butt hinge, the door-side face is completely flat while the frame side has the characteristic twofold wraparound design.
Wrap-around Pivot Hinges
Pivot hinges differ from other models in that they attach to a door's horizontal edge. Hinges that pivot on a pin and bushing install in the horizontal members of the door opening, a simple, reliable option for glass doors and concealed hinges. They typically use a pin and bushing joint in which a narrow cylindrical "pin" rotates within a fitted casing, or "bushing." In a wraparound pivot joint, the frame-side component may wrap partially or fully around the frame.
