The Series 600 Sliding Glass Door features large, unobstructed rolling glass panels that maximize natural daylight and views. Available with panels up to 12 feet tall (or a maximum of 60 square feet), in single opening and bi-parting configurations. It is easy to operate, thanks to sealed stainless steel ball bearing rollers, and the aluminum frame’s clean lines, narrow profile, and high-quality anodized or painted finishes deliver a contemporary aesthetic that seamlessly blends into nearly any space.
