This post is stellar at its one job. It’ll last years and won’t decay.
No need to worry about the vinyl getting too brittle in winter – it can handle normal temperature changes. Acrylic impact modifiers have been added to keep it from breaking or cracking. That said, we don’t recommend banging it with the lawn mower.
The post won’t discolor in the sun – the vinyl contains titanium dioxide to prevent this.
Post has a hollow center. It’s meant to stand alone, but you can insert a 4x4 pressure-treated post if you wish.
