Climbing Monkey Climbing Holds -- 25 Rock Climbing Holds - Premium HD Mounting Hardware Included -- Climbing Rocks for DIY Rock Climbing Wall

You can drill the holes with a 7/16'' drill bit, and the t-nuts hammer in really easily, just make sure to mark the drill spot by sticking a marker down both of the holes. The Allen wrench tightens down the holds perfectly and the bolts are really big and thick. I installed the climbing wall using 3/4" plywood, and the holds felt extremely sturdy with my weight of 200+ pounds, even though I built it for children. The holds are reasonably sized, and simple to grip with hands and feet. Overall I was impressed with this product.Comparatively to other similar products, I like Climbing Monkey Holds because it comes with its own hardware. All you need is a 7/16'' to 1/2" drill bit which you can get at Lowes for like $2.00, and a hammer to put in t-nuts. Also Climbing Monkey Holds have surprisingly long and thick bolts, making you feel much more safe. The holds are colorful and fun so it is great for kids.

These worked perfect for the sized rock wall I needed. I built a 4x7 rock wall and the 25 pcs worked great. They are definitely easy to install and seem to be very good quality. Time will tell how the quality really is but so far so good. My wife and I have both climbed on these as well without any issues.One thing I do recommend, is to use an allen bit with a power drill instead of the one provided (if you have or want to quickly purchase one). I only say this because it definitely saved a lot of time vs having to manually screw down all the bolts (50 of them). I just happened to have one already but using the provided wrench will still work and is simple.

Holds seem sturdy- definitely not pro grade, but great for kids. Fyi The hardware is suuuuper long, for my purposes I had to trim quite a bit off with an angle grinder. Also, the bolts aren't fully threaded, so be careful with your material thickness. All in, they're great, and I'll buy more in the future.

We ended up buying 4 packs of these! Easy to set up, i followed the suggestions online to use a 1'x1' grid, and rotated the 2nd hole at random around the grid layout. Holds work in any direction and provide unique grips. Fun for me at 6'2" and 240 and fun for my 4 & 5 year olds to embarrass me haha.I used a 1/2" auger bit and 3/4" plywood. This whole assembly is screwed to 2x4s securely mounted on the wall. This accomplished 2 things: 1) it's easier to mount and anchor 2x4s than a huge sheet of ply with 32 holds on it, then just zip the sheet into the 2x4s. 2) provides set back distance so the bolts don't mash into the wall.

They're great. I've had them up about 3 months now, no issues. The plastic is very solid.Kids are able to climb them with ease. There's plenty to grab/step onto, not a challenging hold.I agree with the other reviewer who said the 2nd washer is unnecessary, even detrimental. The instructions say to place a washer between the climbing hold and the wall. But if you do this, the hold obviously will not sit flush against the wall, there's a little gap. This adds unnecessary stress on the hold, the bolt, and the wall, making for a less-solid attachment. Can the manufacturer explain why they included this 2nd washer? Is the washer supposed to sink into the wood?Anyhow, scrap the 2nd washer and it is solid! And you get 25 extra washers with your purchase. :)
