Goelst G-Rail's 4200 & 5100 series curtain rail tracks have the essence of a classic pole combined with the precision and comfort of an aluminum curtain rail. This becomes clear with the smooth and almost silent movement of the curtains. These products are easy to bend and with the introduction of a small return allow the curtains to draw back to the wall to minimize light gaps. They are availble in standard colours such as natural, brown, gold, natural polished, and gold polished.
