The QUAD™ railing system is a rectangular post mounted glass system where the glass panels are captured and held at the posts, rather than being mounted at the top and bottom rails as in other systems. This minimizes the number of horizontal rails in the system to allow for maximum visibility. The rectangular posts provide clean lines throughout the system and can be integrated with a grabrail. The QUAD™ railing system is available in both aluminum and stainless steel. The aluminum system provides the ultimate selection in finishes, as the aluminum can have an anodized finish; as well as a powder coated finish.
