TapeTech® Taping Tools EasyClean® 2" Nail Spotters are used to fill the efficiently fill depressions left from nails or screw heads during the installation of the drywall/Sheetrock. The hardened steel skid plate allows the Nail Spotter to move along the wall smoothly while protecting the stainless steel blade from nail or screw heads that were not fully set below the surface of the drywall.
