Retract-a-gate(s) for baby/pets (West woodland)

I have two retract a gate brand retractable baby/pet gates. They are lockable. I have enough original brackets to install one full gate and half of another. You can get some off market replacement brackets online for about $10. Great for the tops and bottoms of stairs. These are not pressure mounted gates. They must be screwed in to the wall, but that is why they are good for up to 200 pounds of push out force. made of materials that can work inside or outside.
