These spikes are designed and engineered to allow traffic to proceed freely in one direction only. They prevent vehicles from proceeding through controlled entry locations by puncturing tires, while also allowing unrestricted passage for vehicles traveling in the allowable direction. Thus, they're effective and economical one-way directional unmanned traffic control.
The spikes are mechanically activated and engineered with spring-loaded teeth, along with a counter-balanced backup system that provides low-maintenance operation. Heavy-duty models feature a thicker (3/8") top plate and heavy steel construction.
