Pivots - Offset Pivots vs Hinges

When a door is hung on a pivot, the entire weight of the door is carried by the bottom pivot resting on the floor
Since the screws in the top pivot are perpendicular to the pivot and at right angles to the opening leverage, the door is hung in sheer rather than in tension
Doors hung on pivots are less likely to pull away from the jamb compared to hinge-hung doors
Offset hung doors assure a snug fit into the opening allowing a weathertight seal using both side and top stops
A bottom seal can also be attained by using a panic threshold
Pivots provide better weight distribution and reduce stress on the door frame
Offset pivots allow for heavier doors and more frequent use without sagging
