Tangkula Offset Umbrella Base 4-Piece Set — 140 lb Stackable HDPE Plates, Water & Sand Fillable

The Tangkula 4-piece umbrella base is a stackable, water- and sand-fillable support system that secures offset and cantilever umbrellas with up to 140 lbs of ballast.

Whether you own a hanging patio umbrella or a cantilever (offset) shade, a heavy, adaptable base keeps it steady in daily outdoor use. This Tangkula set includes four round HDPE plates that interlock and fasten together with metal connection hooks and pins. You can fill the plates with water, sand, or both to reach the weight you need, then stack and carry them easily when not in use.

How much weight can I achieve and how do I fill the bases?

You can reach varying ballast levels depending on fill choice: use water for a lighter, transportable fill, sand for heavier stability, or combine both for maximum weight. Each plate has a large inlet and drain spout with twist caps for quick, spill-free filling and emptying.

• Water only: supports approximately 112 lbs total.
• Sand only: supports approximately 132 lbs total.
• Water + sand: supports up to roughly 140 lbs total.
• Large twist caps make filling and draining fast and tidy.

Will these plates work with my offset or cantilever umbrella?

The set is designed to fit common 9–10 ft offset hanging umbrellas and most 8 ft cantilever umbrellas. Four metal connection hooks and locking pins secure the assembled plates to the umbrella base, reducing wobble and movement under normal conditions.

• Compatible with most standard offset and cantilever frames.
• Four locking metal pins add extra attachment security.
• Tool-free assembly for easy setup on patios or pool decks.

How durable and convenient is the construction?

Each plate is molded from high-density polyethylene (HDPE), a material chosen for outdoor resistance to sun, water and fading. Ergonomic grooved handles allow individual plates to be carried or repositioned, and when empty the plates stack into a compact 12-inch tall bundle for storage.

• HDPE resists cracking, UV fading and water damage.
• Ergonomic handles simplify placement and transport.
• Stackable design reduces storage footprint to about 12 inches tall.

How easy is the setup and what size is each plate?

Assembly is tool-free: align the plates around the umbrella foot, connect with the included metal hooks and push in the locking pins. Each plate measures 19" x 19" x 3", giving a low-profile footprint that still provides ample ballast when filled.

• Plate dimensions: 19 inches by 19 inches by 3 inches.
• Tool-free installation—no extra parts or drills required.
• Low-profile stack keeps umbrella base discreet on patios.

Who this is for: the Tangkula 4-piece umbrella base suits homeowners, short-term renters and venue operators who need a flexible ballast solution for hanging or cantilever umbrellas. It’s a good choice if you want a durable, weather-resistant base that can be light for transport or heavy for steady anchoring, stacks for compact storage, and installs without tools.
