We install this fencing our two dogs inside the passage. When Rauhaardackel I had anyway no concerns that the grid could not fulfill its purpose. When large dog (40 kg) I was already skeptical. In particular, therefore, he has not broken anything prevented him from coming out. But the grid now holds properly for several months. The hinges are made of plastic and act unfortunately not very stable at first glance, yet they hold but without hesitation, even if the dog once supported the front paws on it. To fix we bought a simple metal slide - works.
