Counterweight blocks can be used as ballast for fall protection systems, scaffolding, guardrails, billboards and marquees or façade anchoring. Precast concrete blocks are also used as ballast for tractors or other machinery. At events and festivals with tents, interlocking blocks are used as anchors to increase wind resistance. Concrete blocks with concreted eyelets are also used to set up frame tents on pavement. Using interlocking blocks with forklift slots makes transportation much easier. The ideal solution for temporary counterweights: from scaffolding and fencing at sites or roadworks to the possibility of anchoring during events. The mobile units are easy and pleasant to use and can be stacked for intermediate storage. The stud pattern that connects them is a nice feature that makes it easy to transport stacked blocks from one place to another.
