These safety barricades are made of durable plastic with a water filled base to support a 6 ft x 6 ft chain link fence panel for temporary security. Our plastic traffic barricades can be used for construction sites, military installations, festivals, government facilities, and general security and privacy. This plastic product is lightweight and easy to move when empty. The barricade is filled with water and can be drained before moving. Setup for the safety barricades can be quickly completed with no tools required for installation. The interlocking panels connect together for additional strength.
