The Galvanized Steel Plate Stack Cantilever Base is a robust, stylish solution for anchoring cantilever umbrellas securely while keeping your deck aesthetic clean and unobstructed. Engineered specifically for Ultra cantilever umbrellas, this base allows you to stack weight plates of your choice giving you control over stability depending on umbrella size or wind conditions.

Made from heavy-duty galvanized steel, it resists rust, corrosion, and weathering, so it holds up under rain, sun, and other outdoor elements. Available in both round and square shapes and in several weight options, it’s suitable for residential patios or commercial settings. With a stem height that can be chosen (8″ 18″), it accommodates different umbrella pole heights and designs. Deck-mounted only, this base gives you a clean-look without bulky bases that need frequent repositioning.

Ships made-to-order (4-5 weeks), and designed to last through all seasons. Includes care instructions to maintain the galvanized finish and keep it looking good year after year.
