The document summarizes a wedge barricade, which is a retractable barrier that rises out of the ground to block traffic. It lists the main components of a wedge barricade system, including the barricade, electric motor, sensors, and electronic control unit.

Wedge barricades provide security for places like corporate facilities and military bases by preventing unauthorized vehicle entry. They operate quickly and are reliable, low maintenance barriers suitable for high security locations.
