Here is what I have found out so far:
- The wood ones do indeed split, even with predrilling. Fortunately, the split is localized. However, no telling if it would spread over time. The splits I have seen so far are length-wise.
The way it looks, the contour of the closure strip does not quite match that of the panels.
- The screws that they sell are a bit short (1.25"). I needed at least 2" ones in some places.
