I have 4 safety gates. There are good for cordoning off rooms or parts of a room. They would work for small dogs and other pets and toddlers. These were used very sparingly many years ago. Mostly like new, clean and no odors. I was just in the hardware store and saw these same gates selling for $36 each!
They are about 2ft wide expandable to about 4ft with adjustments in between
5 dollars each
