Description
Single Worm Screws - work best when trying to clear a more solidified type of obstruction such as rags, fats, grease, silt or a severe root mass as these worms can be repeatedly wound into the obstruction like a cork screw to either break up the blockage and let it wash away or retrieve it for disposal.
