Instructions for installing T-nuts

4 prong t-nuts are great for indoor residential climbing walls. They require more time to install than Round Base T-nuts but you'll keep more $ in your pocket! We recommend 100-130 t-nuts for every 32 square feet of climbing wall surface. 4 prong t-nuts are much easier to install with two people working together. Click on the pic to the left for more information on installing 4 prong t-nuts.
For outdoor climbing walls we recommend using Stainless steel t-nuts.
