A Furring Strip is a piece of wood that spaces your plywood panel away from a flat surface. An example would be an interior room that has drywall. Since you cannot attach climbing holds directly on top of the drywall, you need to introduce a 3/4" sheet of plywood. For climbing holds that connect with a 3/8" Allen Head Socket Cap Bolt and t-nut, the bolt must pass through the t-nut and often protrudes beyond the t-nut. The Furring Strip creates the space behind the plywood panel for the extra length of the bolt to pass.
