Well, the concrete base for the 25G 75' tower was poured this weekend and I'm
in the concrete curing process (wetting it down for the next two weeks).
I'm using AB Chance anchors and need 1/2" shackles to go from the screw
anchors to the equalizer plates. I tried to put the two equalizer plates on
either side of the screw anchor eye and use the large bolt Rohn provides for
placing through the eye but the width of the eye casuse the two equalizer
plates to spread too far apart to fit inside the jaw of my turnbuckle. So my
solution was to use a 1/2" shackle from the guy anchor to the equalizer
plate. I went to the local boat store because I couldn't find the 1/2" size
at any of the local hardware stores (Lowes, Hechinger, Home Depot, etc.). I
did find 1/2" shackles at the boat store and was so happy that I bought 3
without inspecting them. When I got home and got one out of the package
there was no rating on it like I had seen on the smaller ones at the harware
store. I assume these are sold at the boat store for anchor chains and are
not rated like the other types. It is galzanized and all it says on it is
"1/2" and "China". Since this will be holding all the force from the three
guys to the guy anchor I didn't want to chance it. Anyone have a good source
for galzanized 1/2" shackles with the proper rating. All I need is 3.
Anyone have any left over from any tower projects that they would like to
part with. Thanks for your help.

Soon to have a signal again.
