The AP 1905 curtain track has a cross section shaped like Piet Hein’s famous geometric figure the Superellipse® and carries his logo. Can be made to measure, and as something unique, has both a wide track and a narrow track. As the first and only in the world, the Piet Hein Superellipse curtain track has a dedicated LED groove, to be combined with our innovative LED light. This allows for the use of Wave gliders. The track is available in 5 unique colors, all of which match Piet Hein’s Superellipse table: Snow, Midnight, Stone, Brushed Steel, Sand.
