Our Custom Gridwork is where we match the panes in your windows. giving your screen the mullioned look that matches your window. Or if you don’t have panes in your glass, some of our customers add the Custom Gridwork to give their windows that appearance. Each section of our gridwork is blind riveted in the back, keeping it from sight but also securing and stabilizing your solar screen. Any gridwork that claims to be adjustable will also move out of place and therefore, easily damaged.
