A wide triple-track aluminum slider with two removable glass panels and one exterior half screen. The side-to-side operating layout is designed for horizontal openings, basement windows, and broad ranch-style units where ventilation is still important. Two-lite units are available up to 96 inches wide, while three-lite units extend to 108 inches wide.
