All: I have about 140' of privacy fence which was installed using these composite post bases (tinyurl dot com slash atbffpe). A problem I have run into is that in really high winds (like during Sandy), the post bases will break, right at the point where the bottom of the 1 1/4" rebar is. I also had several break during another windstorm a few years back. Unfortunately, the fence runs pretty much due north and south, so the prevailing westerly winds (or the easterly winds from Sandy), hit it broadside and generate some pretty substantial loads which the bases and posts need to deal with.
Question for y'all: Has anyone seen anything similar on the market? I like the idea that I have no wood in ground contact (the fence is white cedar), but having to replace 7 post bases is not my idea of a really good time.
