Abstract
A stackable interlocking barrier system includes a first barrier having a front wall and a back wall each extending between a top wall and a floor, at least a portion of the front wall being sloped relative to the back wall. A second barrier also has a front wall and a back wall each extending between a top wall and a floor, at least a portion of the front wall being sloped relative to the back wall. The second barrier is inverted relative to the first barrier with the front wall of the second barrier seated against the front wall of the first barrier. A first connector is removably mounted on the first barrier and the second barrier so as to secure the first barrier to the second barrier.
