Excuse me if these two pics are not properly posted
I hope this comes over ok. Am sitting in hospital while mother in law gets pacer.

You are looking at 13' walls; platforms are 24" deep w about 5 degrees back slope
Flanges spaced every foot w 2' bars
I am super satisfied w it- it was so hard to access lumber horizontally
