Iffin you want to get fancy.
When completed as diagramed you will find that in the lifted position your galv rod will run parallel with the floor at a height of 3 or so inches. Just right for a good trippin!!
If you push the galv to the floor and calculate the angle at the 2x6 you can remove that much angle from the 2x6 so the rod will touch the floor and the 2x6 edges will be parallel to the floor.
I think it makes the whole set up more stable.
