Replaceable fence systems, methods, etc., include at least first and second vertical posts, a bottom rail coupled to the first and second posts and typically having a channel on an upper surface of the bottom rail, and a removable top rail positioned above the bottom rail and coupled to the first and second posts and having a channel on a lower surface of the top rail. The posts and rails are configured to replaceably accept, retain and disgorge replaceable fence panels, typically using a plurality of connection joints that permit the panels to be held at differing, adjustable heights and angles from one post to the next. Each of the channels can include a flexible centering insert configured to accept a variety of thicknesses of replaceable panels.
