A fitted weatherproof cover for a 150 gallon oval stock tank, sized to sit over the tank and protect the water inside from debris, dust and sun exposure. It suits ranchers and hobby livestock keepers who want a simple way to keep a trough cleaner between refills. The cover measures up to 61 inches long, 42 inches wide and 9.5 inches high. It is made from heavy-duty waterproof Oxford fabric with double stitching and an anti-UV coating. Elastic bungee cords at the base help hold it in place in windy conditions, and a loop rope at the bottom lets you add sandbags for extra weight. Reflective strips on the front and back make it easier to spot after dark. The cover is designed to fit most 150 gallon stock tanks, so check your tank dimensions before ordering.
