What is the function of a center hung pivot?

1. To restrict door movement to one direction

2. To allow a door to swing in either direction

3. To provide additional security

4. To simplify the locking mechanism

The correct answer is: To allow a door to swing in either direction

A center hung pivot is designed specifically to enable a door to swing in both directions. This pivot mechanism is mounted at the center of the door and allows it to rotate around a vertical axis, facilitating movement either inward or outward. Such a design is particularly useful in high-traffic areas like double doors in commercial spaces, where the ease of access in multiple directions is essential for efficiency and user convenience. The other options, while they relate to door function or security, do not accurately describe the primary role of a center hung pivot. For instance, restricting door movement to one direction would not align with the functionality of a center hung pivot, which is about permitting bidirectional motion. Similarly, while additional security and simplified locking mechanisms are important considerations in door design, they are not the primary purpose of the center hung pivot itself.
