Material and construction Thickened aluminum alloy track for longlasting strength and corrosion resistance. Builtin nanos material wrapped on all four sides to prevent metalonmetal contact between curtain pulleys and track components, reducing friction and operational noise. Design and function Onepiece doubletrack design: two parallel channels — one for a main curtain and one for a sheer (gauze) layer. Allows layered light control and privacy without multiple rails. Ceilingmount configuration compatible with standard ceiling installations. Performance and benefits Smooth, quiet operation: nanoswrapped edges minimize collisions and noise while gliding. Durable and stable: thickened aluminum resists bending and supports regular use. Spaceefficient and neat: one integrated unit is simpler and more attractive than installing two separate square rails. What's included and installation Complete ceilingtrack kit: track, rollers, end caps, track connectors, and screw accessories. Ready for direct installation by drilling; designed for straightforward fitting without needing extra parts. Compatibility and suitable locations Suitable for living rooms, bedrooms, shower rooms, dressing rooms, kitchens, doorways, or any space requiring layered curtains. Easier to install than two separate rails, making it practical for residential and light commercial use. Practical use scenarios Living room: Hang a blackout curtain on the main track and a sheer on the inner track to switch between privacy and natural light while maintaining a quiet, smooth glide. Bathroom or shower room: Use the double track to separate a waterresistant curtain from a decorative sheer, keeping the decorative layer dry and clean. Dressing room or bedroom: Install as a ceiling track for a tidy, professional look that supports daily use and reduces noise when opening or closing layers.
