Guardian's Cobra traffic spike systems are designed and engineered to allow traffic to proceed freely in just one direction. The Cobra's purpose is to prevent vehicles from proceeding through controlled entry locations by puncturing tires while allowing unrestricted passage for vehicles traveling in the allowable direction.

Cobra traffic spike systems provide an extremely effective and economical one-way directional, unmanned traffic control. Systems are available for surface mounting or in-ground installation. All Cobra products are mechanically activated and engineered with spring loaded teeth along with a counter-balanced back-up system that provides reliable and low maintenance operation.

Guardian's Enforcer motorized traffic spike systems provide reliable access traffic control by electro-mechanically moving the teeth up to an active or secured position, and then down to allow unrestricted passage to authorized vehicles. The self-contained modular system allows design flexibility combined with easy installation in manned or unmanned sites. Enforcer can be installed in new or existing facilities and is easily integrated with multiple access control options.

Enforcer is ideal for parking lots, airports, auto dealerships, car rental agencies, government installations, commercial and industrial sites or other secured locations where a high level of access control is required.

Guardian's Stinger pedestrian-friendly concealed traffic spike system is engineered and designed with below-grade spikes that will puncture the tires of offending vehicles while providing above-grade, non-penetrating teeth. The below grade tooth stays submerged until activated by wrong-way traffic. Only then is the spiked tooth deployed, puncturing the tire of the offending vehicle. The Stinger is ideal for shopping centers, amusement parks, schools and private communities where a large amount of pedestrian traffic exists.
