The Galvanized Steel Stack Base is a sleek, high-performance umbrella base engineered to keep your outdoor space looking clean while offering serious stability. Designed for center-pole umbrellas (with 1.5″ or 2″ diameter poles), this base allows you to stack up to three galvanized steel plates (“G-Plates”) to adjust weight according to umbrella size and wind conditions.

Constructed from galvanized steel for enhanced corrosion resistance, the base withstands rain, sun, and harsh weather without rusting or deteriorating. With stem height options between 8″ and 18″, and several weight classes to choose from, you can tailor the base to your umbrella and setting. Matte silver finish adds a modern touch that complements most patio decors. Perfect for both residential and commercial use, this base delivers both form and function. Deck installation only.
