PB 3308815 Black Neoprene Support Blade for Minuteman / Power Boss Scrubbers. Neoprene is used in cases where the standard duty tan gum blades won't hold up and distort. Neoprene blades are naturally chemical and oil-resistant and can be used in food processing plants, chemical plants and areas where tan gum blades might be affected by chemicals. They are also naturally chemical resistant and can be used where caustic chemicals exist. Durable and abrasion resistant neoprene inner support blade for Minuteman / Power Boss. This black neoprene support blade measures 58-3/8" x 3-5/8" x 1/4" with 9 mounting holes. Fits newer style Minuteman / Powerboss scrubbers including 8290 Combination Sweeper/Scrubbers (82 Series - TSS/82, ISS/82, CSS/82), and 9082 Double Scrubbers (82 Series), Commander 82 Series (C82, T82), and Monitor 82. Older models require a 54-3/4" blade (3301637) or a 59-1/8" blade (3300334, 59-1/8" with 18 holes) instead of the 58-3/8" neoprene blade listed here. Please check your model before ordering.
