50 lbs Universal Umbrella Base


50 lbs Universal Umbrella Base

I’d like to meet the “engineer” that came up with the picture with the dimensions for this.
I’m wondering how from the top of the “stem” to the base it is 16" and the base is 3"…They come up with an overall height of 18". 16 + 3 = 18? I don’t think so.

Depends on what part of the base is being measured to…
Look at the pic. There is a rise toward the center, my guess is that is the missing/overlapping inch.
