Well It seemed to work fine and fit the Umbrella,  but my Umbrella is a heavy 10in and 8 feet. But by the end of the summer,  the winds caused the Umbrella to tilt over on my deck railing the other day. The base pole bends and comes out even with the Umbrella removed. The base is covered at the bottom not allowing you to tighten the bolt from underneath ~
I cant even store it in the garage upright for the winter as it tilts and sways~
Now have to get a new base, heavier and 3 times the amount just to get one at 75 pounds or above ~ So disappointed!
