this large umbrella mount for my floating dock..very robust build but be careful as it was not cleaned off of metal filings from the manufacture. Got a very small aluminum splinter in my hand that went pretty deep but got it out. Wear gloves and file any sharp edges. The very small and weak so called handle made no sense?? It's useless. Drilled my umbrella pole to match the posts pre drilled holes, then used a 1/4\" trailer coupler pin to secure the umbrella...no worries with the umbrella being lifted from the post. Gave negative 1 star because of the splinter it gave me.
