    Post end cap

    Works fine. Could have been more impressive to look at. Seems too flat. Needs more height.

    Perfect fit for the post sleeves I purchased through Deck Expressions. Very happy... You should offer a way to upload pictures so I could show a before and after

    Looks as good as the original. Easy to install. I couldn't tell from the picture when I ordered if the "underbelly" of the deck post cap was integral; therefore, I ordered the base trim as well -- didn't need it. My current post caps had separated, so I thought two pieces were the way it came and are required.
