The Steel Drag Mat is the easy way to make sure your court stays healthy. Dragging it over the court is the equivalent of 56 blades scraping over it in a single pass. High & low spots are leveled, surface is turned over, algae never has a chance to set in and hard spots are removed before you notice them! We recommend regular use - once or twice a week - to keep your court at peak performance. It can even be dragged over lines that are flush with the court's surface.
