You don’t have to sacrifice looks, function or quality when you’re looking for 4x4 post caps for your fence or deck railing. Our brown 4x4 fence post caps come from the slimline series of plastic post caps, our most economical and budget-friendly post topper product line. The addition of these fence post toppers will enhance the beauty of your landscape and protect your posts from age-related erosion, and any potential weather damage your fence support posts may experience. The brown 4x4 post caps in the slimline series are only available in the nominal size. What that means is that the description on the label refers to the measurements that the mill made when cutting the posts from green or undried wood. Cutting wood to size when it was green used to be a common practice back in the days before we had precise machinery that makes it easy to cut wood after it dried. Green wood is still moist, so it shrinks during the drying process. That means that the 4x4 posts that bear the word nominal on the shelf tag, product sticker or advertisement are really 3.5” x 3.5” posts.

Unlike wood, ASA resin doesn’t shrink and expand with humidity fluctuations, and it won’t weaken because of the continual atmospheric and moisture changes throughout the year. ASA resin requires no maintenance, and that will never be the case with wood post caps. And one of the greatest benefits of our plastic post caps is that we’re selling you a superior product line for a fraction of the cost of comparable wood fence post caps. And they’ll last far longer, too.
