Stainless Steel Car Hook 1/2 x 8 Inch

What is the diameter of the top of this hook? I need to see if it will fit over an existing pipe I have.Thank you.

What is the diameter of the part that would hook over something? We are wanting to hook it over a pipe and was wondering if it would hook over. Thanks!

I need the hoods to fit over a 2" diameter pipe. Is the inside diameter of the hood 2" minimum?

Awaiting response
