Double Barb Arm

Double Barb Arms are heavy-duty fence extensions designed to hold multiple strands of barbed wire above chain link or perimeter fences. They are manufactured to ASTM, DIN, and ISO standards using carbon steel, stainless steel, or aluminum. Available in V-shaped and Y-shaped designs, they provide maximum wire coverage and enhance perimeter security. With galvanized, powder-coated, or stainless steel finishes, they offer excellent durability and long-term corrosion resistance. They are widely used in industrial fencing, high-security perimeters, agricultural enclosures, and military or correctional facilities.
