Tangkula 4-Piece Fillable Patio Umbrella Base — 208 lbs Stackable HDPE Plates for 9–10 ft Offset Cantilever Umbrellas, Black

The Tangkula 4-piece fillable umbrella base is a heavy-duty, stackable HDPE plate set that adds up to 208 lbs of ballast to stabilize 9–10 ft offset (cantilever) umbrellas.

Built to reinforce your cantilever umbrella without taking up permanent space, this four-plate system stacks over a separate cross base (cross base not included) and accepts water, sand, or a mixture to reach the weight you need. Each plate locks into the next without metal pins, has a built-in spout for easy filling and draining, and nests compactly for storage. The black, weather-resistant HDPE construction resists cracking and keeps the set looking neat on patios, decks, and poolside areas.

How much weight can I add and what filling options exist?

You can choose water, sand, or a combination to reach different ballast levels depending on wind conditions. Filled with only water the set reaches 128 lbs; with only sand it reaches 168 lbs, and with a water-and-sand mix it reaches a maximum recommended 208 lbs.

• Water: 32 lbs per plate, 128 lbs total
• Sand: 42 lbs per plate, 168 lbs total
• Water + sand combined: up to 52 lbs per plate, 208 lbs total

Will this base work with my offset (cantilever) umbrella?

The Tangkula set is designed for 9–10 ft offset umbrellas and is intended to be placed over a compatible cross base (not included) for best stability. The interlocking plates increase ballast and reduce movement while remaining adaptable to common cross bases used for cantilever umbrellas.

• Recommended umbrella size: 9–10 ft offset/cantilever
• Requires a separate cross base or stand to hold the umbrella pole
• Interlocking design secures plates without metal pins

How easy is the setup, transport, and storage?

Each plate is lightweight when empty and includes a hidden handle to move it easily. The plates align and lock together for a stable stack, and when emptied they nest to save space in a garage or shed.

• Empty net weight: 18 lbs total (about 4.5 lbs per plate)
• Hidden carry handles for effortless transport
• Stackable plates reduce storage footprint when not in use

Is the material durable enough for outdoor use year-round?

The plates are molded from high-strength HDPE, a plastic known for resisting weather, UV degradation, and cracking under normal outdoor exposure. While manufactured for outdoor longevity, store or cover the plates during extreme cold or prolonged storms to extend life.

• Material: weather-resistant, high-strength HDPE
• Black finish complements many umbrella colors and outdoor décors
• Designed to withstand regular patio and poolside environments

Who is this for? The Tangkula 4-piece fillable umbrella base is for homeowners and property managers who need a flexible, heavy-duty ballast solution for 9–10 ft cantilever umbrellas without committing to permanent concrete or heavy unmovable stands. It suits anyone wanting adjustable weight options (water, sand, or both), easy seasonal storage, and durable construction for patios, yards, decks, and poolside seating areas. Note: cross base required for umbrella insertion and is sold separately.
