Perfect solution for our umbrella stands! It is slightly taller than original pipe on stand (this is a plus!) Has two bolts instead of one (Another plus) to help secure the umbrella better. Has two rubber reducers to fill in gap around the umbrella pole. Only issue is the shank on the bolt is too long (bolt that secures pipe to base). Extra bolt was too short. We are purchasing another one for another umbrella stand. Great price for the product! And was easy to install, keeps the umbrella straight and upright!

Good quality, but likely holds water.

Good quality and was easy to install on base with two bolt lengths provided. I modifed by drilling a small hole through the base of the pole mount so that water can drain out. I have previously ended up with a rotten wooden umbrella pole because the pole mount held water!

This is the one to buy

It was the perfect replacement heavy duty constructed and able to take different size umbrellas.

Good fit, but loosens easily

Fit perfect but the wind blowing makes the whole umbrella move the part enough to loosen it so continually having to tighten, which is a pain since you have to do so from the bottom of the base.
