Thanks for all the nice comments! 

Hi Tom, they seem to carry the load okay so far.

Hi Larry, the ladder brackets are pretty much standard ( 1" diameter and 11 to 11 1/2" centers). The variable is where the ladder is placed on the back of the unit. The first one I made was for a ladder 17" from the back corner. This one is 4" from the back corner so I made it the same length and put 17 holes in it compared to 12  the one made earlier!!

Hi Ducky , if more are needed I'll put them out in a few hours. They are too long to keep in inventory!!
