Outsunny 4-Piece Heavy Duty Cantilever Umbrella Base Weights - 264 Lb Capacity, Weatherproof Design

Keep your cantilever or offset patio umbrella stable and secure with this heavy-duty 4-piece base weight set. Designed for easy filling and dependable wind resistance, the set adds substantial ballast to compatible 9–10' offset umbrellas and is built to last with weatherproof HDPE construction and textured surfaces for improved grip.

• Product Dimensions: 20.9 L x 21.3 W x 16.9 H (inches) — each weight unit; four-piece set stacks and fits a 39.37" x 39.37" (100 cm) cross base for most 9–10' cantilever/offset umbrellas.
• High Capacity: Achieve up to 264 lb total weight when filled with sand (approx. 66 lb per unit) or up to 176 lb with water for strong wind resistance.
• Durable Construction: Molded from thick, weatherproof HDPE to resist cracking, UV exposure, and rain for season-after-season reliability.
• Anti-Slip Design: Grooved exterior surface increases friction between the weights and the umbrella base for enhanced stability compared with smooth designs.
• Easy to Fill & Empty: Each unit features a twist-off spout cap for quick filling and a watertight seal; spouts also simplify draining for storage or transport.
• Universal Fit: Designed to accommodate offset/cantilever umbrella cross bases measuring approximately 39.37" x 39.37" (100 cm); individual units stack and secure under the base.
• Low Maintenance: Simple wipe-clean surface and no special upkeep required—store empty in winter to prolong service life.

Features

• Cantilever Umbrella Weights: Our set of umbrella base weights offer a design built to fit an offset patio umbrella 9-10' tall with a 39.37" x 39.37" (100cm) cross base.
• Heavy Duty Umbrella Base Weight: Add weight to your patio umbrella to help windproof it. Our umbrella base weight set can weigh as much as 264 lbs. with sand or 176 lbs. with water.
