Barriere place that easily, I liked the "always unlocked" or the timer to automatically open or close, and then automatically Latched. Very easy to install and above all moved wherever you want as you want thanks to several possible positions of the closure bar. Perfect pr up my stairs, opens easily even with BB in the arms, we manage to open it with one hand. The price is high, but if you want a roll barrier without discrete threshold and hyper, I suggest.
