Tropitone SP20R15 20" Round Steel Umbrella Base with 9" Sleeve are designed for durability, convenience and maneuverability. The style you choose is purely personal. However, the size, shape, environment and wind conditions where your market umbrellas or patio umbrellas will be located must be factored into your selection from our range of umbrella bases and umbrella stands. This heavy duty base is intended for use under Tropitone dining tables, or as a stand alone base. Pair with a Tropitone Aluminum Umbrella or a Basta Sole® Patio Umbrella for the perfect outdoor design statement.
