Originally purchased system to block my door, I was a little disappointed that the ring does not not completely block the door but remains "soft", so we can still move the door, but of course without closing, so the finger protection function is confirmed! But I thought that would be really locked the doors so disappointed because my little good fun to make things door returning against the wall with the effect of an elastic ... Fortunately, it ended up interest something else ... A tip: this system is also very suitable for sliding wardrobes, simply pinched between the walls and this immobilizes the sliding doors. I could not find a system to block my various cupboards, finally I found it by chance!
