PB 3318528 45" 5 Double Row Nylon Patrol Main Sweeping Broom for Power Boss 72 Series Sweepers. A very open configuration of nylon filament designed for higher speed collection of stubborn litter and debris. This 5 double row configuration has more space between rows for capturing difficult to collect trash, cans, litter and pallet waste. For longer wear, look to the 24SR high density broom (3318526). Fits Minuteman Power Boss 72 Series Sweepers, including SW/72 and SW/72 Deluxe. Replaces Minuteman Power Boss 3318528, 318528.
