We have a granite umbrella base weighing 80 kg (176 lbs). Since we need to move it frequently depending on the sun’s position, having wheels would be practical.
Now I’m wondering if and how it’s possible to install wheels myself? I have already researched this but found varying opinions. Unfortunately, I couldn’t find anyone who has done this themselves and can share personal experience.

So far, this is what I have gathered:
  • Wheels can be attached either by screws or by adhesive
  • When drilling, maintain enough distance from the edges, at least 3 cm (1.2 inches)

What remains unclear to me is whether gluing or screwing is the better option. Also, I would prefer wheels that do not rust. However, I could only find galvanized wheels, none made of stainless steel. Does anyone have a recommendation?

I had four holes drilled by the stonemason and had four M10 threads installed. Then I got four casters with M10 threads and screwed them in. They hold very securely and meet my expectations perfectly.
