DDAC is a below-ground fence system that protects commercial and residential structures against invasive wildlife and keeps pets from digging out of yards. This innovative exclusion product is easy to install and cost-effectively addresses problems that previously mandated back-breaking hardware cloth buries or repeated trapping. DDAC is a simple, quick, trenchless, humane, drive-in permanent barrier underground that protects foundations, decks, sheds, electrical substations, zoos, barns, ranches and more. Made in the USA from 4-gauge galvanized steel, each DDAC unit measures 15 in. tall by 4 in. long; tines are spaced 1.25 in. apart. Once installed, it protects properties from skunks, opossums, raccoons, porcupines, foxes, groundhogs and other animals that love to dig.
