Standard window handles are window grips or handles used to open and close windows. They are made of various materials such as metal, plastic, or wood, and are available in different styles and finishes. Standard window handles are typically attached to the window frame and have a lever or button that can be turned to open and close the window. They are often used on windows made of wood, aluminum, or PVC and can be used on both inside and outside windows. Some standard window handles also have a locking function to lock the window.
