Practical Round Umbrella Base Weight Bag Key benefits Stable and safe: Adds 10–15 kg of ballast to prevent umbrellas, tents or signage from tipping in light to moderate wind, protecting people and furniture. Easy to use: Hook-and-loop (magic pad) sealing lets one person open, fill and close the bag quickly—no tools required. Space-saving and reusable: Foldable design stores flat when empty; reusable construction reduces waste compared with single-use alternatives. Versatile compatibility: 8 cm diameter center hole fits most standard umbrella and pole sizes used for garden umbrellas, patio parasols, market tents and temporary billboards. Features and specifications Shape: Round umbrella base weight bag for even weight distribution. Sealing: Hook-and-loop (magic pad) closure for quick, secure sealing. Center hole diameter: 8 cm, designed to accommodate common pole diameters. Capacity: Holds approximately 10–15 kg of sand, gravel or other ballast per bag; can be filled on-site. Reuse and storage: Foldable for compact storage; designed for repeated use. How it solves common problems Prevents tipping: Adds reliable ballast to lightweight bases that can otherwise lift or shift in wind. Simplifies setup: No heavy or fixed bases needed—bags are filled where you use them and emptied for transport.

Practical use scenarios Backyard patio: Place one or two bags around a garden or patio umbrella base to stabilize it during outdoor gatherings. Market and event tents: Secure tent legs at farmers markets or craft fairs where temporary, portable ballast is needed. Outdoor signage and billboards: Add weight to temporary advertising signs or displays at events to reduce accidental tipping. Notes for use Fill with clean sand, gravel or similar ballast up to recommended capacity (10–15 kg) and secure the hook-and-loop closure. Ensure pole diameter is 8 cm or smaller to fit through the center hole; verify fit before full installation. When empty, fold flat and store in a dry place to extend product life.
