Looks great
This looks great on our new mailbox and post.  It comes pre-drilled with some very small holes.  The pre-drilled holes would probably only fit a finish nail, but going into a plastic post that would not work.  So I drilled the holes out a little to get them to where my screws could slide through, then also took a countersink bit and drilled it so the screw heads would not stick out.  The pre-drilled holes were a nice guide and of course PVC is easy to drill.  For a slight improvement to the product I would include screws and holes that fit the screws, with a countersink so the screw heads are hidden.  Even if you are going into a wooden post I would suggest screws over a nail if you want it to stay attached.
