What is the function of a swag or swage hinge?

The function of a swag or swage hinge is primarily to allow doors to swing in both directions. This type of hinge is specifically designed with a pivot point that enables a door to open from either side, making it ideal for applications like commercial spaces or double doors in residential applications. These hinges facilitate ease of movement in areas where traffic flow is unidirectional and can enhance accessibility.

In terms of design, swag hinges have a unique shape that accommodates this bi-directional movement without compromising the door's stability or alignment. As such, the design prevents issues like sagging associated with heavier doors but does not primarily function to reduce space when doors are closed or support weight alone. This versatility in motion is what distinguishes swag hinges from other types, emphasizing their specific application in scenarios requiring dual-swing functionality.
