Zep: I think I can see why it can't be made into a "T", but why couldn't you take a 20' long 6' wide section and put it crossways at the end of the walkway? Use the same posts to anchor it down. Or, is there a limit to the lengths of the posts?
Scott you would think that would probably work.
It does say on their dock page that...
Poles are available in any length up to 20' But I don't think that would be an issue in my pond.
I almost afraid to ask what shipping costs from Michigan to Texas would be?
