It is intended for professional use in support operations and mobile workshops, particularly in competitive environments where the stability of temporary structures is critical to safety and operational continuity. The set includes 4 black GT2I Race & Safety water-filled ballast bags, intended for ballasting the legs of tents or canopies.
