The wall clamp with telescopic bar is a good product, unfortunately the wall terminal was not enough for our old building balcony, they should be made larger, not only 19 cm. The telescopic poles we can use super and so far everything is quite safe. At least we have a good feeling when our Stubentiger are on the balcony. Can I easily recommend, but only for balconies with a ledge to 19 cm. Please measure. Simone
