Anti-climb spikes are sharp metal or plastic nails installed on the top or edge of a fence, primarily to prevent break-ins. They are designed to physically deter intruders by causing injury, and also serve as a visible warning to discourage potential trespassers. Anti-climb spikes are typically made from plastics such as polycarbonate and polyethylene, or metals such as hot-dip galvanized steel and stainless steel. Some products are available in custom lengths (e.g., 1 meter, 1.25 meters, 2 meters, etc.). Large anti-climb spikes are stamped and formed in a single process, ensuring a sharp, rigid tip. They are primarily used in locations requiring security, such as residential walls, prisons, and border checkpoints, and are attached to the top of fences or metal barriers using expansion screws.
