Each barricade can be folded, stored on a warehouse shelf and transported to the work location as a compact package. Simply attach to corner eyebolts or fold out in the drift, connect valve up to air bottle or compressed air via a reducer valve and inflate.
Once fully erected, secure the barricade to the back and walls by the quick snap on buckles. In the picture to the left, there is a double door to allow personnel to enter or exit the blocked off area. The door is held closed by velcro strips on the sides and the bottom and provices blast damage relief in areas close to the main excavations.
