A butt hinge is a common type of hinge used to connect two objects, most frequently a door to its frame. It consists of two identical metal plates, or leaves, connected by a barrel-shaped knuckle in the center. When closed, the leaves lie flush against each other.
Understanding Butt Hinge Components and Functionality
- Two Identical Leaves: These plates are attached to the door and the door frame (or other surfaces).
- Knuckle: This central part allows the leaves to pivot smoothly, enabling the door to open and close. Butt hinges typically feature a larger knuckle than other hinge types.
- Installation: Butt hinges are usually mortised, meaning they're inset into the door and frame for a clean, flush look. One leaf is attached to the fixed object (the frame), while the other is connected to the moving object (the door). They provide a limited angle of rotation between these two objects.
Types and Uses of Butt Hinges
Butt hinges are incredibly versatile and are used in a wide range of applications, including:
- Doors: Interior and exterior doors, cabinet doors, and even gates.
- Cabinets: Commonly used for kitchen cabinets, bathroom vanities, and other furniture.
- Other Applications: Any situation requiring a robust and reliable hinge that provides a flush appearance.
There are variations, such as rising butt hinges which lift the door slightly as it opens. Standard butt hinges are typically six inches or shorter.
Butt Hinges vs. Other Hinge Types
While other hinge types exist, butt hinges stand out for their simple design, ease of installation, and robust construction. Their flush design provides a clean aesthetic, making them a popular choice for many applications.
