Enhance your outdoor seating with the Resin Umbrella Base with Filling Cap from Grosfillex, crafted from 100% prime resin for exceptional durability. This base is designed to fit seamlessly under any Grosfillex® table, offering stability and support when used in conjunction with tables. To ensure optimal weight and stability, it must be filled with water or sand to achieve a weight of 35 to 40 pounds. The prime resin material is naturally impervious to moisture, salt air, and chlorine, ensuring it will not peel, rust, or stain. Built-in resin glides protect your terrace or deck from marks, while two thumb screws securely anchor the umbrella pole. Easy to maintain, this base can be effortlessly cleaned with soap and water, making it a practical and long-lasting addition to your outdoor space.
