We have applied our distinctive styling and quality construction to a standard style of sliding, lift out window.

Front View

Side View

Our WC-300 Single Slider window has a 4 1/2″ fusion welded frame and only one sash that slides horizontally within the frame with the other sash fixed. The normal slide is from left to right (viewed from the outside) but the opposite slide is available (must be specified when you order) and the sash lifts out for easy exterior cleaning from the inside. This window comes with a half screen that is on the end that opens only and is easily removable.
