Glass-to-glass hinges are a type of hinge designed to connect two glass frames together, allowing them to pivot or open and close like a door. The hinge is usually made of metal, such as stainless steel or brass, and is attached to the glass panels with notches. Glass-to-glass hinges are commonly used in frameless glass shower enclosures (showers), where they allow the shower door to swing open and close. They can also be used in other types of glass doors, such as cupboard doors or room and space dividers. One of the advantages of using a glass-to-glass hinge is that it provides a sleek and modern look, as there is no visible frame or hardware between the glass panels. In addition, the hinge allows the door to open and close smoothly and easily, while providing stability and support for the glass panels.
