A paumelle is a type of hinge that is used for opening and closing doors. The word "paumelle" is derived from the French word "pommelle," which means "ball." This type of hinge has a round knob or ball on one side and a hole or eye on the other side, through which it can be attached to the door or window frame. Paumelle hinges are often made of steel or heavy cast iron and are designed to be strong and durable. They are used for heavy doors such as interior or exterior doors, as they are able to bear the weight of the door while providing a smooth movement. Paumelle hinges can also be used on other types of products such as windows and cabinets.
