Split arm operators are specialized hardware used to control the opening and closing of casement windows, most often installed in wood, vinyl, or aluminum frames. They feature a dual-arm design - ne arm attaches directly to the window sash, while a secondary 'split' arm provides extra stability and leverage. This configuration ensures the window opens and closes smoothly and securely every time. Weather Shield casement windows and other leading brands rely on these operators for their dependable, precise movement.
