8x8 Post Caps

Actual vs Nominal

There is no escaping the fact that an 8x8 wood post is massive. Its sheer size means that the fence those posts are supporting is going to create a dramatic impact. Whether you’re looking for post caps that will protect your valuable posts, or you want to protect them and add an elegant decorative element to rev up the impact, our 8x8 fence post caps will do all of that and a lot more. 

8x8 Post Caps

Our ASA resin post caps, come in two styles: the pyramid top estate series, and the plateau (flat top) series. Our 8x8 pile and post caps are made of polyethylene, another type of hard plastic. We also carry 8x8 metal post caps that are made out of aluminum.

The ASA resin post caps are exclusive to Atlanta Post Caps. And they are the only patent-holding fence post caps on the market. ASA Resin is the material of choice for the automobile industry, and if it’s good enough to withstand the abuse that cars take, we’re confident it will withstand the damage that nature inflicts on our ASA resin 8x8 fence post caps

**Atlanta Post Caps guarantees the purchase of ALL ASA Resin post caps for ten years against fading, warping, or discoloration.**

ASA Resin is superior to wood for many reasons, including:

  • Will outlast wood by a long shot

  • It costs a fraction of what comparable wood post caps cost.

  • Won’t warp

  • Won’t contract and expand - which wood does because of humidity fluctuations.

  • Won’t decay over time.

  • Won’t attract gnawing animals or wood-eating insects

  • Doesn’t require any maintenance - and our post caps won’t ever need new coats of sealer. 

We carry two sizes for both the Estate and Plateau series. Both series 8x8 post caps come in nominal and actual sizes.

Nominal is the term that the lumber industry coined to describe wood posts that are cut when they’re green. A nominal 8x8 post is true to size when it’s green, and before it’s cut. Nominal posts are cut and then dried, and the drying process removes excess water from the green wood. A precut post will be a half an inch smaller on all sides after drying.

The lumber industry uses the term Actual to distinguish between posts that are dried before they are cut. Actual describes posts that are true to size when they’re cut because they were dried first.
