US Weight 80 lb Umbrella Base

The US Weight 80 lb Umbrella Base is a free-standing patio accessory designed to secure market umbrellas in outdoor settings. Its high-density polyethylene shell resists rust, dents and fading while the prefilled 80 pound concrete core provides substantial stability. Removable wheels and hand grips allow one person to move the base across decking or lawn. The unit arrives new and ready for immediate assembly.

Shoppers needing a mobile heavy base

This base suits homeowners who want a single, wheeled foundation for a large patio umbrella and prefer not to fill a hollow shell with sand or water. The 14 inch stem accepts poles from 1 ½ to 2 inches thick and includes a plastic post protector that prevents screw damage. Buyers who require a lighter base for frequent repositioning or a smaller footprint for tight balconies should consider alternatives. The Proposition 65 notice indicates the presence of listed chemicals.

14 inch stem with dual knobs

The 14 inch high stem is the critical fitment dimension; it determines which umbrella poles can be mounted. Two polypropylene knobs clamp the pole securely without marring the finish. All steel hardware uses grade 304 stainless steel for corrosion resistance. The 20.5 inch diameter concrete-filled shell delivers the stated 80 pound weight that anchors the assembly in wind.

Questions about this item

Do I need to supply my own umbrella pole, or is one included with the 80 lb base?

The base is sold without a pole. You must provide a patio umbrella with a pole diameter between 1 ½" and 2" to fit the 14" high stem.

Will the 20.5" diameter base and 80 lb weight stabilise my existing cantilever umbrella?

This model is designed for centre-pole market umbrellas only; the stem clamps a straight pole and is not compatible with offset or cantilever frames.

How can I confirm the base is holding the umbrella securely after I tighten the two polypropylene knobs?

The pole should sit on the internal plastic post protector with no wobble, and the grade 304 stainless stem should remain vertical when you gently shake the canopy.
