Question: I want to install these on 3/4" plywood. Do I need 2 1/2" wood screws or 3"? Or am I better off going with bolts and t-nuts? And what size and length
Document: These things are soooo coool! I bought 50 to cover 2 walls in my 2 car garage and soon discovered that I needed more, so I ordered another box. They are really much better than the actual holds you can buy from rock climbing outfitters because #1 the price, and #2 the size of them.
Wow! Very impressed with the quality and selection of this package. Shipped quickly and plenty of holds for our 7' tall x 12' wide rock wall. Strong odor persisted for 2-3 days, however, no issues after that. Highly recommended.
My wife and I built a playset for our 3 year old son. The climbing holds specifically made for children are usually larger, made of plastic, but also very expensive (per piece). These holds look like real rock, are easily to install, and our son has no trouble scampering up the wall using these holds.
Several different shapes and sizes. Only a few were too small / grabs were too narrow for kids to use (prob. great for advanced climbers). Used regular deck screws to attach to decking that I installed up the side of their playground. After six months, there has been no noticeable fade or deterioration -- and the kids love them.
Love this product. Looks like real rock.I decided the climbing wall could be used as a witness tool for God. I wrote words of inspiration on each rock (Examples: faith, hope, courage, pray, love, give, joy, inspire, shine, forgive, believe, God....). At the top of the wall I added a picture I painted on slate of a cross with the words &#34;4 ME&#34;.
I was nervous to purchase these because I wanted them for a children's gym, but I was very pleasantly surprised when I got them. The holds are big enough to be realistic for an older kid, but small enough and varied enough to make things a bit challenging.They look like authentic rocks. The kids think they are way cooler than those regular colored kiddie rocks. They are easy to install. I might have to buy a few more though since the wall turned out so great.
The grips were perfect for our sons rock climbing wall. Built well and easy to install. Love the natural grey color.
These climbing holds feel and look like real rocks.Very sturdy and look great on the wall.Only 4 stars because they were very dusty when they arrived. My advice is to open the box outside and hose them off. Once rinsed off, they were easily a 5 star item.
I soaked them in a bucket of water for a day and then let them sit in the sun for a week. After that, there was no more smell.
good product. all shapes and sizes. built a wall for my kids and these holds work perfectly. very durable. I would definitely recommend buying these since they are priced extremely well.
