Richard - Thanks for your help. I went on line and accessed Anvil's November 2011 catalog (Pipe Hangers and Hardware Catalog) here:
http://www.anvilintl.com/Literature/Catalogs.aspxThe load tables are on P. 144-145 of the document.
I have a number of hangers for which I pre-defined the spring rate because the cans exist and I wanted to see what their new rating might be due to changes we are making. Here's an example of what CAESAR reports for one of the hangers I predefined. There are other hangers I predefined for which CAESAR gave similar recommendations. In this case it was a type 98 size 7 (56 lb./in.). The 50 lb./in rate that the program is selecting shows up in a size 8 triple or size 9 quad - is CAESAR recommending either of those two as alternatives? If so, then the message is that the current cans can't be re-used (reset).
