That was easy
So far it holds (2 weeks)
Unfortunately, it doesn't look quite great with the edge of the curtain, you probably have to glue something there.
But otherwise to divide something in the room top

actually didn't sticked but I used screws to hold on and are perfect now, to every 1m have 10 holders for clips with two ends and o e extention for every 1 m. still awesome

Everything from Temu Gardine, Curtain Tape, Curtain Hagen especially for this rail.1.50 cm comes disassembled into three parts each 50cm, I myself have a little over 3.00cm.
Between each part is a connector to plug in, can be shortened well, even with very sharp fabric scissors.The glue holds bombproof as you can see in the photo. I glued the adhesive strip to the privacy screen, not to the ceiling, because there is already a large slat blind hanging there. I put two photos in it, feel free to take a look.
