Your umbrella will stay anchored in either the 55 lb. (19W 19D 14H) or 110 lb. (23W 23D 18H) base. Use with the outdoor dining tables. The heavier base is suitable for freestanding umbrellas and is only offered in black. The smaller base is available in beige, black and champagne bronze. Also standard is the sleeve that accommodates poles of up to 1.75” in diameter.
