However, there are many wall spikes models which consist of a 4-sided razor comb and are designed to rotate when grasping or climbing on it. Thus, making it impossible for the individual or the animal to cross it and enter your premises. And you can place it vibracrete walls, existing perimeter walls, & fences. On the other hand, car spikes have no specific design, but the spikes are sharp to deflate the speeding car’s wheels.
