Ruby Interior glass sliding doors offer architects and designers the freedom of choice between a top hung sliding glass door system and a pivot system. Ruby's unique all glass door system ensures minimal obstruction from hardware and framing to provide customers with the largest viewing area through the glass with a clean finished appearance. The Ruby Pivot System has a high-tech appearance and can be used as a free swinging door or the swing can be controlled by adding a floor closer. PRL's Ruby Pivot system is available with overhead panel and sidelight connectors, which give the freedom of adding a transom and/or sidelights to your opening. The Ruby is suspended from above, leaving a trackless and uninterrupted floor.
