The Rohn hinged baseplate for Rohn 25G is item number BPH-25G.
It is held onto the base by four 1/2" x 12" J-bolts but none of the
drawings spell out the bolt pattern layout dimension. Since the base
plate is 15" square, I am guessing the holes are on 1" x 1" centers
or 13" from hole to hole. Is this correct?
My thought is to take a plywood square, drill the pattern, mount the
J-bolts and then when the concrete is ready, wiggle the plywood jig
in place and level it. When it dries I remove the plywood and the
base is ready to go in. Should work unless I have the bolt spacing
wrong. Does anyone know?
