This "pen" is just the "gate" I was looking for, at a GREAT price.  It's just right height & width for the specific area that I want to keep my four small dogs out of.  I found a wooden one that was the right width, but I had to step over it.  I looked at so many "gates", but couldn't find one, not one, that didn't require the added expense of purchasing additional panels for extension.  And because this is flexible, it doesn't have to be attached to the walls or doorways.  I will be purchasing additional "pens" for a few other areas that could benefit from them, indoors & out.
