When there's no snow on the ice, use the Clam® Fish Trap Skirt Snake to hold down your fish traps and ice houses. Simply fill the tubes with sand and lay them across the ice house's skirts to keep your ice house securely in place. Each package comes in a package of three, with each Clam® skirt snake holding 10 pounds of sand. This innovative design ensures that you can worry about ice fishing and not about your ice house. Try the Clam® Fish Trap Skirt Snakes this ice fishing season.
