To temporarily slow down the Zuglust on a staircase, I had the choice to install a cornice or to use a telescopic pole. As the curtain is quite difficult, I had my concerns that the telescopic pole to slide down or, at worst, could crash repeatedly. But as I lay neatly beside it, because the telescopic rod keeps wudnerbar and even if one pulls pulls the curtain or she moves no mm. Incidentally, a little tip: To adjust the rod to the circumstances, they should be max. 1cm further pull apart, as to bridging distance measures. This cm generates the spring pressure! If you have taken the whole thing by mistake too far apart, you screwed the caps left and right on the bar and pulls the whole inner part out completely. Then you put this back on the other side of Au0ßenrohres, pushes it through, the cap is on again and hey presto, you can adjust any number of times, again.
