Best Choice Products7.5ft Heavy-Duty Round Outdoor Market Table Patio Umbrella w/Steel Pole, Push Button Tilt, Easy Crank Lift - Green

What is the actual diameter of the pole? It's either 1.5" or 2". It's helpful to know so we can buy correct base. The answer of 5" doesn't make sense.

What type of base would i need to purchase for this to sit by itself? (Not inside a table)

Does it come with a cover?

Could you cut off a section at the bottom to shorten it slightly?
