NOSTIFY 25 Pcs Colourful Pig Nose Shape Rock Climbing Holds with Blue & Green Auxiliary Handles, Indoor Outdoor Playground Wooden Play Set Build Exercise Toy Accessory - Mounting Hardware Kit Included

I have an existing bouldering wall that is the same specs as any gym or professional wall. The hardware that came with this set is not the correct size, this may only be an issue if you are trying to add kid holds to an existing wall. I hammered in one of the Tee nuts before realizing they weren’t the same as my others and my existing hardware wouldn’t fit. If you buy this just for the holds, those are fine for kids, cheap and good value for young ones. If you are adding or building a wall to use real holds on, don’t use this hardware, buy bulk tee nuts and bolts of the correct size.
