Baby Gates (Hastings on Hudson)

I'm looking for two baby gates that my son can put on the top and bottom of his staircase for my recently crawling grandbaby. We're looking for the kind that fastens to the walls and swings open like a gate and which does NOT have a bar on the bottom under the gate, itself. Here's an example on Amazon of what we're looking for: https://www.amazon.com/dp/B005SESNAM/?tag=thewire06-20&linkCode=xm2&ascsubt...
