[TowerTalk] J bolts and Plates

[ISP BNJCOMP COM]

I am trying to put up a SSV tower and have aquired leg bolts from Nello.  Problem is that they were suppose to be "EXACT" replacements for ROHN J bolts but they are not.  Instead these are straight bolts that take "plates"  between a couple nuts at bottom of bolt  in concrete.  Nello kind of ripped me off as they did not supply exact replicas but then they want to charge me another $500 to get an engineered plate for the bottom of bolts for my tower they sent me.   

So I am trying to find these plates and the specifications on them for similar towers.  IN all honesty I would like to find much bigger towers with plates at bottom and then just use the bigger plates to insure the tower is over engineered.    I guess I could look at Rohn specs on the J bolts and see how much surface area each of them have in the J portion and make sure I exceed that..

Nello tells me that Rohn is only Company that uses J bolts and everyone else uses these bolts and plates.  So I figured there has to be some specs out there.   Any help would be appreciated.

If you ever buy something from Nello that is suppose to be "exact" replacement I would strongly suggest you get drawings and check it yourself as they have some pretty funny "replicas".
