This retractable gate was used at the bottom of a staircase. It does indeed block it from small children. I didn't find anything else like it.Installation of course varies with the construction of your home. I had to adapt to make this one work. A more flexbile mounting would be nice. Expect some customization if the mounting sufaces aren't flat and uniform.Unfortunately, the device no longer automatically retracts after less than 1 year. Attempts to contact the manufacturer so far have been ignored. This device failed when it wasn't even in use. Don't expect high reliability.
