[TowerTalk] Rohn Anchor Block Data

[DMartin560 at aol.com]

Hi Group:

In looking at Rohn drawing number C620643(R13), Standard Concrete Anchors, 
I'm trying to determine the depth of the anchor block.  That is, the distance 
from bottom of concrete anchor block up to finished grade.
There is a dimension line (D) shown on the drawing, but no dimension given in 
the chart, nor any reference in how to determine it.
Am I missing something?

Thanks,
Dwayne
