    Post end cap

    Posted by Len Collier on Aug 6 2021

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

    Product Review

    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.
