Check out Portland Bolt- They helped me out when I needed anchor bolts
for my 72' tower. Reasonable and quick

I have started digging the hole for installation of a used US Tower MA-40 with MARB Rotor
Base. I contacted US Tower for a quote on four 3/4" X 27" anchor bolts but they
say that is not a stocked item so lead time is 6 - 8 weeks.
If I wait 8 weeks to get the bolts then 28 days for the concrete to cure that
means 3 months before I can get the 3 element SteppIR in the air.
Do any of you structual engineer guys out there know what specification J bolt
is needed and a good source. Shipping will be to northern California.
I said J Bolt but I know US Tower is now welding two nuts and a washer to the end of
the 27 " bolt. Don't know if that is a structual improvemet over a J bolt or
just easier to manufacturer.
