We have two swing gates...both are the mount kind...one for the kitchen and one for the hallway. I like the kitchen one the best..it doesn't say who makes it, and i don't remember. I got it at walmart for a great price. You could use it tension set, or swing...and choose which way it swings.
The hallway one is by Safety first. I don't like it at all. It is hard for the kids to open and close right...and just not as functional for us as the one in the kitchen. I think we are going to take it out, and get one like the other one, even though I hate making more holes in the wall. I have a wooden tension gate in front of the bathroom where the cat litter boxes are...so far he hasn't chewed through those, but he is not back there much. He chewed through the first one like that we had in the kitchen. That is when we went out to buy the heavier plastic kind that he couldn't chew through.
I want to look for the one like Lexi's mom talked about. All the ones like that I have seen in the past had too big of a space between the bars. Brinkley could have gone through them as a pup. Maybe not now. A friend of ours got one like that and her husband installed a piece of clear plexiglass across the front b/c their yorkie went right through the holes.
