WaterWarden Pool Safety Fence 4' x 12', UL Certified to ASTM F2286 Safety Standards, Removable, Easy DIY Installation, Black Protective Mesh Netting with Black Frames

I did something like that for my kids’s kids. Bought a 3/4” hammer drill and bits at Harbor Freight. Less than an hour we had a functional fence. Lots of other good ideas here, too. Can’t be too safe! https://a.co/d/06MJMhfP
