Review on 🧗 Unleash Endless Fun with TOPNEW Climbing Indoor Outdoor Playground by Patrick Hamilton

Uncertain. I mounted them on a climbing wall outside and within a week the finish was coming off on a bunch of screws, they would rust, which would be bad enough, but they also don't hold tight enough to the wall with one screw at a time. keep and a smooth back. Twice while climbing with these holds, the hold twisted and dropped me to the ground. Glad it was me and not the kids. I can't get enough of this product, the studs are not stainless and rust easily and the holders can't hold an adult motionless when they are new, give it a couple of months and I doubt they would hold my kids.
