Coyote Roller (Roller only, mounting brackets are sold separately)

I bought a full set of these will all the necessary hardware. I installed them so that they faced inside just to keep the cats on the patio (we don't have coyotes here, I'm in the city). The cats tried to jump one time, and then never again. For two years I've had them and can now safely trust my cats on the porch while I do chores in the house. I absolutely love these. They have made it through snow, heat, and hurricane winds without any issues. These are amazing. No more chasing the cats to keep them from running into the road (when when I was sitting with them, they would wait until I turned my head to LAUNCH themselves over the fence and run free). They were easy to install with a drill and table saw (or other cutting device. Having a second person hold them in place while you drill helps, but I likely could have done it alone. I can't say enough nice things about these.
