The Master Court Drier from RolDri features a durable polyvinyl alcohol 36" roller with a seamless construction that will out perform any other roller. This non-deteriorating roller is molded directly onto the roller core for a seamless fit and a unique "rolling seal" action that continually squeezes water ahead of the roller and adapts to the contours of the court. To remove the majority of water, use your Court Dryer to push the liquid out of the area of interest. This requires little to no downward pressure on your RolDri as it move forward or backward. Tough and durable, non-deteriorating 36" polyvinyl alcohol foam roller. Produces a clean 36" wide sweep that squeezes water ahead of the roller. Rolling-seal action doesn't skip depressions.
