Klein featured their new Extendo 3 telescopic door system at the 2012 AIA Convention last week in Washington D.C. These space saving, acoustically-sound doors have no floor tracks and the upper tracks can be recessed as well. Glass panel thickness is 3/8 in or ½ in. With a silver-anodized aluminum profile and a ball bearing system for soft, quiet openings, the doors are ideal for conference rooms and offices. Featured here is a four-sided cubicle configuration.
