Secure outdoor umbrellas to a base that is easy to attach and relocate with the Global Industrial Umbrella Base made of concrete. Sturdy in both construction and design, this base can be used to house any outdoor umbrella with a pole of up to 1.5" in diameter. Plastic insert adapter allows the base to fit most umbrellas. Umbrella base is slightly heightened by small feet to keep the base off the ground so dirt and moisture do not get trapped and discoloration of the floor surface does not occur.
