Bull Barn's Marauder Fence keeps digging, burrowing vermin at bay. A 16" apron can be folded along the hinge joint to the inside or to the outside of the installed fence. The 16" apron folded inside the fence line works great for dogs that dig under fences to get out. The 16" apron folded along the outside of the fence line works great to exclude burrowing animals from getting into pastures or crop fields. The apron fence is attached with a hinged joint, allowing the fence to flex over terrain and under foot. The 4" x 6" mesh openings should be folded outside of the fence for livestock that could get hooves caught. This 4 foot height works well to enclose most livestock. Add an extra line of electric fence or barbed wire for taller animals. The Fixed Knot is the most secure knot in the business. Fewer fence posts are needed to maintain a strong fence when using high-tensile wire. Graduated spacing keeps horizontal line wires closer together at the bottom (which deters small animals from crawling through the bottom) and further apart at the top. This low-maintenance fence is guaranteed for 20 years. Keep deer and predatory animals out; keep farm and ranch animals safely in.
