This Square 4-Piece Cantilever Parasol Base from Christow is perfect for stabilising cantilever and banana parasols with a cross-base height of 4.5cm to 6cm. The base consists of four parts which form a decorative square shape when fitted together. Each part of the base can be filled with water or sand to provide your parasol with strength and stability. When filled with water, each part weighs 15kg with a combined weight of 60kg. When filled with sand, each part weighs 20kg with a combined weight of 80kg. The base is made from weather-resistant, high-density polyethylene for long-lasting use. Metal U-locks allow you to secure all four parts of the base together and prevent them moving around. The U-locks can only be used to secure parasols with a cross-base height of 6cm. They cannot be used to secure parasols that have a cross-base height that is less than 6cm. Size of each individual section: 50cm x 50cm x 7.5cm. Note: Cross-base does not come included with the cantilever parasol base.
