General Information

Pivot sets (both offset and center hung pivots) are recommended for high-traffic interior or exterior doors, or any door where appearance is an important consideration. They are expecially useful for extra-heavy doors. They have the ability to carry a lot more weight than butt hinges. The HardwareSource.com website has both Offset Hung Pivot Sets and Center Hung Pivot Sets on its website.

Advantages

The weight of the door is supported entirely by the bottom arm, which is connected directly to the pivot spindle. This means that the fasteners on the door and frame are in shear rather than tension (as with butt hinges). The fasteners are less likely to loosen over time. Because the weight of the door is supported entirely by the bottom pivot and the floor,  it creates a door hanging system which produces less stress on the frame assembly, prevents your door from sagging and makes for a door that opens and closes with less friction.

Offset vs. Center Hung Application

Offset pivot hinges have a hinging action which is simliar to a butt hinge. The pivot point is located off of the surface of the door. The pivoting hardware on a door installed with a center hung pivot hinge is completely concealed except for the floor plate (it is possible to conceal the floor plate with flooring).

Intermediate Pivot

An intermediate pivot hinge (see illustration above) is required for doors over a certain height. This is required to make sure the door stays in proper alignment.
