This incredible expanding, rolling fence goes from just under 2 feet to a whopping 17 feet with just a tug. Sturdy and durable, it's a reliable barrier against pets, deer, even young children! Keep prized plants and containers safe from curious hands, paws, and nibbling teeth, or corral the family dog into one area for safety and peace of mind. Also comes in handy as a privacy barrier between your patio and your neighbor's. Central post prevents sagging when fulling expanded, and locking casters prevent bumps from creating gaps and openings. Span can curve or run straight and true. Use multiples to create a large enclosure, indoors or out.
