Unique and innovative way to grill hot dogs. Hot dogs are placed in a "corral" that moves up-and-down over a heated fat grill surface. Dual thermostat. As the hot dogs turn, they roll in their own juices producing a self-basting hot dog that sears in all of the natural flavor. Built with our commitment to quality, the Roundup Hot Dog Corral will give you many years of dependable, trouble-free service. The Model HDC-21 features two heat zones for maximum productivity.
