   Uh, the thickness of the metal is less important than the dimensions of the ell.  You need to support 800-1000 pounds.  There are some calculators online, but I haven't worked my way through them.

   no way

   just too check.

   section mod = 0.56

   moment = = w*lsq/8 = 52k

   w= about 20# inch  =  12 in long block, 4 courses * 60 # block?

   l == 144

   52k needs to be less than  20ksi*0.56  = no

   now, the 20ksi is code allowable, yield say 70ksi 

   still likly to bend unless reall light weight block (< 10#/block)
