What is the primary function of a strap hinge?

The primary function of a strap hinge is to support heavy gates or doors. These hinges are designed with a long, flat strap that extends along the surface of the door or gate, distributing the weight more evenly than standard hinges. This design allows strap hinges to bear significant loads while maintaining the structural integrity of the door or gate. They are commonly used in applications where durability and strength are vital, such as on barn doors, heavy wooden gates, or large entry doors.

While other options may seem plausible in specific contexts, they do not capture the primary function of strap hinges as accurately. For instance, while strap hinges can be adapted for lighter doors, their primary design purpose is not for light doors, but to effectively manage the weight of heavier structures. Similarly, although some design elements can enhance aesthetics, strap hinges are primarily functional, serving to provide robust support rather than focusing on visual appeal. Lastly, the option about covering gaps pertains more to architectural finishes rather than the core utility of strap hinges, which is centered around supportive functions.
