9 umbrella base

Common supported pole diameters include about 1.3", 1.5", 1.9" and up to roughly 2.0" on some models. In other words, most bases cover standard market poles through about 2.0" in diameter — check the product listing for the exact size compatibility.

Filled capacities vary widely by design: small recycled-rubber bases can be around 27.9 lb, many plastic/HDPE fillable stands range about 48–64 lb when filled with water or sand, and large multi-plate cantilever bases can advertise total filled capacities up to about 274 lb. Verify the specific product listing for its quoted filled weight.

Many fillable bases include molded or grooved handles to lift them, and some wheeled stands have casters to roll the base. A few models list wheels with two brakes so you can lock the base in place after positioning.

Bases for cantilever/offset umbrellas often list cross-brackets or specific base-hole/anchor spacing (for example, a 9" spacing) and will note compatibility with 9–10 ft offset or cantilever setups. Confirm the listed spacing and compatibility for your umbrella model.

Common materials shown in listings include resin, 100% recycled rubber, polyethylene (HDPE), and other plastic constructions, with material choice varying by base style (fillable reservoir, plate, or solid pre-weighted design).

Assembly requirements vary by model: some require adult assembly, some include the necessary tools, some need no tools, and others note tools are not provided. Check the product listing’s assembly instructions to know what’s required.

Common securing features include adjustable tightening knobs or collars that clamp the pole. Some fillable bases also include a post or insert you attach after filling to hold the umbrella pole securely in place.
