After a first ambush (impossible to remove the essential element to add extensions), still very well managed by Amazon, the second barrier is not better received. We managed to install it with great difficulty, and arrangement of extensions is very very strange, roughly once installed, all that is not very right. Furthermore, the opening to a hand is simply impossible. Basically, a fence and practical extensions for a big opening like ours when you do not want to drill into the wall ... but at the same time the only solution, all other major barriers for wall mounting! I do not recommend if a choice is possible.
