SSBRIGHT Sets of 25 Multi-Colored Kids&Adults Large Rock Climbing Holds Climbing Rocks for Outdoor Indoor Home Playground DIY Climbing Wall Grip Kits Holds up to 440lbs with Secure Mounting Hardware

The threaded supports that go behind the plywood are a little bit on the cheap end. I threaded the bolt through with my drill to suck the bracket tight to the back of the plywood and some of them stripped, BUT once I predrilled the holes and pounded the brackets in with a hammer instead it worked a lot better. Only thing I recommend is to not drill the holes to 1/2 like the directions explain. You can still mount the bolt bracket on the back and run the bolt through the front with a smaller hole. This creates a more sturdy support and you dont have to worry about your bracket pulling through the plywood. Overall nice product though.

I use these daily on my outdoor rockwall. Its a great workout. My husband also used them.

Easy to install on a 6x8 ft fence panel we had in the back yard. Grandkids havent tried it yet. You do need access to both sides of the wall and a second person is helpful.
