Vinyl casement windows are attached (or hinged) to one side of the frame and open by swinging out from your home. Great Lakes Window vinyl casement windows open with a crank and feature a fold-away nesting handle that does not stick out and provides a nice, tidy look. Our casement windows also offer a single-lever multi-point locking mechanism with single locking handle for maximum security.
