The set of four Sand and Water Filled Cantilever Bases from Nova is the ideal solution for supporting your cantilever parasol. The base is made from heavy-duty plastic which not only ensures long-lasting quality but is also easy to carry, clean and stores away. The base is made up of four triangular sections which each fit into the cross-section base of a cantilever parasol to provide support and stability. Each section should be filled with kiln-dried sand and water for maximum support which equates to 20kg per triangle, a total of 80kg. We recommend using the funnel provided to fill the sections with ease, we also suggest part filling the triangles with sand and then saturating them with water.
