Homeowners, patio owners, and poolside hosts who need a genuinely heavy, weather-resistant base for a large offset umbrella will find this 4-panel HDPE refillable base engineered for exactly that purpose.\u003c\/p\u003e\n    \u003cp\u003eThe base consists of four interlocking HDPE panels (40 × 40 × 2.8 inches assembled) connected by metal lock pins. Empty weight is 18.94 lbs. Each panel is fillable with water or sand — reaching up to 120 lbs per panel when filled with water, and a total filled weight of up to 220 lbs with sand. The HDPE construction resists UV rays, oxidation, corrosion, and cracking through extended outdoor exposure.
