This type of hinge is specifically for glass doors. With its U-shape, it is designed for the glass between 4 and 6 millimeters thick. To install the cap, a 9-millimeter hole is required in the place where it will be pressed. Also, the screws included with the hinge will press hard on the glass to prevent it from slipping out of position. It is made of stainless steel with an aluminum painted finish, making it durable and aesthetically pleasing. In each lot, 100 hinges are supplied for the right side and 100 for the left side, for a total of 200 units in each package.
