The Rohn flat base plate is designed to be used with one pier pin, in the hole 
centered between the 3 legs.

I've found some of these with an extra hole out near the edge -- maybe for 
attaching a rope for carrying. Others I've seen have had four smaller holes out 
hear the edge,  apparently for bolting to a concrete base rather than using the 
pier pin.

The idea of the single pier pin is that the tower can rotate on it when it is 
twisting in the wind -- rather than twisting the tower itself.
