Abstract
A control barrier includes a barrier wall having a front face and an opposing back face each extending between a top end and an opposing bottom end, a first recess being formed on the front face at the bottom end of the barrier wall. A first slot extends through the barrier wall from the first recess to the back face. An elongated first leg is coupled with the barrier wall so that the first leg can selectively rotate and can selectively slide. A first foot is mounted on the elongated first leg, the first foot being selectively movable between a first position wherein the first foot is at least partially disposed within the recess of the barrier wall and a second position wherein the first foot is rotated a least 45° relative to the first position and is removably positioned within the slot extending through the barrier wall.
