What do you get when you combine a rolling base, heavy-duty concrete, functional features, and materials built to last? The only umbrella base you'll ever need! This base is made from solid concrete to add maximum durability and stability to any umbrella with a whopping 80lbs of support. That durable concrete is encased in weather-resistant plastic to last many seasons. With this, one base fits most as it's built to accommodate most market umbrellas ranging from 6-11ft (pole diameter: 1-1/8in - 2in). But we've saved the best for last. What's better than built-in handles, an adjustment knob, a rolling base, and the 2"" receiver tube? How about locking wheels?! That's right, you can freely move your umbrella to shade your patio and garden with locking wheels for safety. There are too many reasons to make this umbrella base yours.
