One of the most common door hinges is the butt hinge. Butt hinges are composed of two identical leaves – one that’s attached to the moving component and the other on the fixed component. They’re attached by a curled barrel, also known as the knuckle, which allows the door to open.
One of the major reasons they’re common for entry doors is because they’re designed to support a lot of weight. Many steel, wood and fiberglass doors can be heavy which can damage weaker hinges. However, butt hinges won’t buckle under the weight.
There are several different types of butt hinges available, including:
Lift-joint butt hinges: easy to separate the door slab from the frame – simply remove the center pin.
Rising butt hinges: made for rooms with uneven floors
Ball bearing butt hinge: made for heavier doors
