An elegant and traditional umbrella base. It features the patented Dual-Purpose Stem, which allows you to use the base with a free-standing shade umbrella or reduce it to use under a table. The base is comprised of a cast aluminum shell with a cast iron center base and weighs 50 lbs. A 30 lbs. Add-On Weight option is available and recommended for free-standing applications. Available in several finishes to coordinate with our umbrellas. For our larger umbrellas, we also have a 2" diameter stem option.
