Made by Raumplus, this set features three frosted glass, aluminum frame doors that can slide to one side or the other. Each single pane door panel runs in an independent channel on top & bottom track (included at Customer Service). I don't think this kit was ever installed, but it has been in storage for at least eight years since we sold it the first time. It's picked up some dust and dirt along the way, but still should clean up o.k. Meant for interior use.
