4 Prong T-NUTS

Standard 3/8"-16 zinc plated


T-nuts


Standard 4 prong T-nuts are made with thin .063 or .071 material thickness.



At Three Ball Climbing we recognize the fact that t-nuts were not originally designed for use in climbing walls.

In cooperation with one of our hardware vendors we have developed truly heavy duty .075 material thickness 4 prong t-nuts.

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.
