Heavy-Duty Cantilever Umbrella Support
Fillable Stability for Large Outdoor Umbrellas
Four modular HDPE weight plates provide a practical foundation for compatible 10–15 ft cantilever umbrellas on patios, decks, gardens and poolside areas.
A Stable Foundation Without a Permanent Installation
Fill the individual plates after positioning them around a compatible umbrella cross base. The modular construction makes the empty plates easier to handle, position, drain and store than a single solid base.
Three Filling Options
Choose water, dry sand or wet sand according to the weight and stability required for your outdoor setup.
Four-Piece Design
Four separate plates fit around a compatible cross base and can be emptied individually for seasonal storage.
Outdoor HDPE Construction
Durable high-density polyethylene construction is designed for regular outdoor use around patios, decks and pools.
Choose the Right Filling Method
The final base weight depends on the filling material. Select the option that best matches your umbrella size, outdoor location and seasonal needs.

Frequently Asked Questions
How does the base reach 330 lb?
The approximate 330 lb maximum applies when all four plates are filled with wet sand.
Does the package include an umbrella?
No. The package contains the fillable base plates and center cover only. The umbrella and metal cross base are not included.
Will it fit every cantilever umbrella?
No. Compatibility depends on the umbrella cross-base dimensions and the clearance around any rotation pedal or control mechanism.
Should I use water or sand?
Water is easier to drain, while dry or wet sand provides more weight for a longer-term outdoor installation.
