Our 4-Plate Refillable Umbrella Base is the perfect blend of modern aesthetics and heavy-duty performance. Designed for those who value both style and safety, this base ensures your outdoor oasis stays shaded and secure throughout the year.

• ‌【Extreme Stability & High Weight Capacity】 Designed to keep your cantilever offset umbrella secure in all weather conditions. Once filled, this 4-plate base weighs up to 120 lbs with water, 160 lbs with sand, or a massive 220 lbs with a sand-water mixture. This heavy-duty support ensures your umbrella remains upright and stable even against strong winds.
• 【Premium Weather-Resistant HDPE Material】Crafted from high-density plastic (HDPE), our patio umbrella base is built to last. The material is UV-protected, fade-resistant, and waterproof, preventing cracking or aging in extreme sunlight or rain. The classic black textured finish complements any outdoor decor without the worry of rust or corrosion.
• 【Effortless Filling & Watertight Seal】Each panel features a wide injection port and a secure twist-cap for quick, mess-free filling. The leak-proof seal prevents evaporation and ensures the weight stays consistent over time. Whether you use water or sand, the installation is smooth and tools-free.
• 【User-Friendly Portable Design】 No more struggling with bulky weights! Each plate is designed with an ergonomic carrying handle for easy transport. When the season ends, simply drain the plates and stack them together. The **space-saving, stackable design** makes storage in your garage or shed incredibly convenient.
• 【Perfect Fit & Enhanced Safety】Measuring 40" x 40" when assembled, these 4 interlocking panels fit most cross-base offset umbrellas. The set includes 4 metal pin connectors to lock the panels firmly in place. The bottom of each plate features ventilation holes and high-friction molding to increase grip and prevent sliding on your deck or patio.
