Review on Enhanced Protection: Set of 2 Cast Iron Door Stops with Heavy Duty & Low 🚪 Mounted Rubber Bumper Tips for Kitchen, Bedroom, Office - Easy Installation Ensures Wall and Door Safety by Rich Fiedler

I also bought a cast iron doorstop from John Wright but overall I prefer this version of the A29 which is also now cheaper. Screw A29 is concealed and mounted in the middle. As another reviewer mentioned, I didn't use the screw that came with it. It is somewhat long and narrow, with a flat head. Even after pre-drilling the holes I thought the assembly would be too risky as my heads sheared off or broke. It can also be difficult to remove if painting is required. The heads are hidden anyway. Also note that the base of this stop has a small ledge (where it meets the wall). I'm guessing the idea is to stop this from spinning, but that means you'll end up with another hole. It seems a little pointless to me.
