The Ostro slabs provide optimal stability for your cantilever parasols, even in windy conditions. Their clever design allows for centered positioning on the base cross, ensuring perfect balance and enhanced safety.
With a water fill, each slab weighs 25kg, providing adequate weighting for a 3x3m parasol. By adding sand, the total weight can reach 120kg, offering ideal stability for models up to 3x4m.
This plastic is made from post-consumer recycled material, meaning it was originally used as new plastic, then melted down and reformed into recycled plastic pellets, and finally moulded into slabs or ballast tanks. The composition of this product is certified by our GRS (Global Recycled Standard) certificate.
