Ostro set of 4 weight slabs

Charcoal grey

Autobloquantes.svg Optimal stability and security

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.

Eco 1.svg An eco-friendly choice

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.

With this new product, Armand Serafini has successfully solved the everyday usability challenges reported by our customers. But that’s not all: he has channelled his creativity into crafting soft, harmonious lines that blend seamlessly with the parasol. The anthracite grey finish perfectly complements our parasol frames.

Compatibility

The Ostro slabs are compatible with the Aura centre-pole parasols (all sizes) and the Mistral cantilever parasols (all sizes).

Sturdy and easy-to-handle slabs

The simplest and most efficient way to secure your parasol. This set of 4 slabs, designed to be filled with water or sand, ensures optimal stability for your Belveo parasol, giving you the peace of mind to enjoy your space. Each Ostro slab features indented handles, making them easier to move.
These slabs are compatible with both Belveo centre-pole and cantilever parasols. However, due to their large size, we recommend them primarily for cantilever parasols. The perfect balance of value and performance to equip your outdoor setup.
