A double curtain rail is a functional hardware system featuring two parallel curtain tracks or rods, allowing for the simultaneous, independent hanging of two curtain layers—typically a sheer, voile, or lightweight fabric on the inner track for daytime privacy/light filtration, and a heavy, opaque, or blackout curtain on the outer track for night-time privacy, insulation, and room darkening.
Double curtain rail tracks hame a standard length of six metres.
The price of double curtain track is per piece.
