PB 3303741 14" .070"/46 Grit Super Abrasive Scrub Brush with Lugs for Power Boss Scrubbers. Our heaviest grit for aggressive scrubbing of unsealed or older sealed concrete floors with heavy dirt and debris. The heavy grit brushes can also be used for stripping finish and sealers from sealed concrete flooring. Long lasting DuPont Tynex-A or Hahls Nylon filaments are impregnated with large 46 grit silicon carbide granules and are arranged in a 6 row configuration on a solid plastic molded brush block. For a slightly less aggressive brush, search for 3300795, .050"/80 Nylo-Grit. Not recommended for polished concrete, painted or epoxy painted flooring. Usually brown, orange, purple or grey in color. Include 3 drive lugs (arranged around a 5-1/2" center hole). These are the older style scrub brushes used on models including 62, 65, 78, 80 and 82 Series scrubbers. Please check your model before ordering. For the newer PowerDrive style clip-on brushes, use 3313127. Most machines require 3 brushes (4 if using a side scrub brush). Priced each. Replaces Minuteman / Power Boss 3303741. Our Part Number PB 330374
