Class #150

It's just a sign of 20 ft container rigging bucket.

I don't know why it's put there, because this term is normally used in piping for 150 psi pressure. Not for container.

 

I thought it will be better to focussing on cross #, but the final not give as expected.

I suppose to focus on 150 ! :(

 

Just levelling and (cross process) curving.
