Our black 4x4 post caps are part of the slimline series, our most economical line of plastic post caps. They serve two primary purposes: protecting your wooden support posts and beautifying your landscape, and there is no question that these fence post caps will fulfill those functions and do it well.

The slimline series is only available in the nominal size. That means that these plastic post caps will fit 4x4 posts that indicate that they’re the nominal size. The lumber industry uses that term to distinguish between lumber that’s cut when it’s green (nominal) as opposed to wood that’s cut after it undergoes drying. Wood that’s cut in its green state loses a half an inch during drying. That means that a nominal 4x4 is in fact, a 3.5” x 3.5” post.
Our 4x4 post caps in the slimline series are made of ASA resin, the same hard plastic resin that car and marine vehicle manufacturers use when making their products. The material is prized for its UV and impact resistance, among other qualities. It won’t get discolored, fade, or warp, and we stand by that contention with a ten-year warranty on all fence post caps made of ASA resin, guaranteeing them for that period against warping, fading, or discoloration.
ASA resin plastic post caps are superior to wood in other ways, too. These hard plastic fence post caps will withstand anything that Mother Nature throws at them - literally, including gigantic hailstones, or projectiles that tornadic and hurricane force winds hurl through the air. They won’t experience the repeated contraction and expansion pattern that wood does from humidity changes. That continuous cycle of shrinking and expanding weakens the wood over time. Our plastic post caps cost considerably less than their wood counterparts, and they’ll last far longer than wooden post caps do, too.
Installation of our ASA resin fence post caps is a breeze, thanks to our patented two-part SNAP-CAP installation system. The two parts consist of a sleeve that slides ¾” down the wood post from its top. The post cappers sit on top of the post, and the two pieces attach with screws that will never show. Once the snap cap is installed, the 4x4 post caps will measure 4.5” x 4.5” at the widest point.
