Four-plate offset umbrella base

This square base consists of four detachable HDPE plates that stack for compact storage. Each plate measures 20" x 20" x 3" and weighs 18 lbs empty. The set is designed for offset umbrellas equipped with a cross base.

Sand or water fill changes stability

Filling the plates with sand raises the total weight to 180 lbs, while water brings it to 130 lbs. Each plate has its own fill spout and twist cap for quick, separate filling. The heavy-duty HDPE resists sun damage and cracking.

41-inch assembled footprint

When the four plates are arranged together, the base covers 41" x 41" x 3". This footprint supports 9 ft and 10 ft offset umbrellas in windy conditions. Buyers needing a single-piece base or a smaller footprint should look elsewhere.

Questions about this item

Will the HDPE plates crack or fade after years in the sun?

The base is made of heavy-duty HDPE plastic that is sun-protection treated to prevent cracking and is designed for easy maintenance.

How much weight can I actually get on the base before it stops adding stability?

Each of the four plates holds sand for up to 180 lbs total or water for up to 130 lbs total, which is the maximum ballast the design provides.

Does the base get hot enough to burn bare feet on a summer afternoon?

The black HDPE plates absorb heat in direct sun, so the surface can become warm; consider a cover or shaded placement for all-day comfort.
