These awning operators are constructed of high pressure diecast zinc and the case and crank come in a bronze-colored baked enamel finish. Each operator features a simple detach clip which allows the operator to disengage from the sash's center hook for quick and easy window release. This awning operator mounts on the bottom window sill of crank out awning windows, and holds the sash open at the user's desired location. These operators replace others whose roto gears may have become worn and stripped, or the spline to which the hand cranks attach. Included with each is the operator, a crank, a sash hook and installation fasteners.
