Heavy Duty 4 Prong T-nut specs


  • Our 4 Prong Heavy Duty T-nuts are great for indoor and outdoor, residential and commercial climbing walls.

  • We recommend a minimum of 130 t-nuts for every 32 square feet of climbing wall surface. (You'll need 128 if you create a 6" x 6" grid.)

  • Holes for these t-nuts should be 7/16" diameter.

  • * Warning * 1/2" drill bit is NOT "close enough" in size to 7/16". T-nuts installed in 1/2" holes will be structurally compromised and will no longer be safe for use.
