Actual vs Nominal

Any wooden fence or deck railing is a significant and investment you make for your property. And 6x6 timber posts are large enough to attract attention. It makes sense from a financial and aesthetic standpoint to protect that investment. We carry 6x6 post caps that are made of ASA resin, PVC, and aluminum. We sell two styles of ASA resin 6x6 post caps: the Estate (Pyramid-shaped top) Series, and the Plateau (Flat top) Series. We carry plain slim profile pyramid-top aluminum 6x6 fence post caps, and solar-powered LED lighted 6x6 deck post caps. We also sell decorative PVC solar plastic post caps that have an antiqued electroplated copper finish. 

All of our 6x6 fence post caps are designed to slide over the top of your wooden posts. They create a seal that will prevent water from seeping in and saturating the tops of your posts, potentially leading to mold growth or rotting. Whether you’re looking for fence post toppers for the dual or triple purpose that some styles serve, or for pure function, our line of Atlanta Post Caps 6x6 post caps will fulfill those goals and much more.

ASA Resin Post Caps

Our ASA resin 6x6 deck post caps are superior to most post caps in the industry. They’re made from the same hard plastic that automobile manufacturers use for bumpers and other car parts. ASA Resin’s use in cars is definitive proof that the material can withstand everything from harsh weather conditions, to projectiles that fly through the air during hurricanes and tornadoes. ASA resin is durable enough to tolerate the intensity of UV rays. 

ASA Resin post caps carry the Atlanta Post Caps label. We’re proud of the superior quality of all of our plastic posts caps, and the fact that they are made in the U.S.A.

Our plastic post caps carry a patent because of the ingenious design of our SNAP-CAP installation method.

Every purchase of our ASA resin 6x6 post caps comes with a ten-year guarantee against fading, warping, and discoloration.

ASA Resin 6x6 Fence Post Caps come in two sizes: Nominal and Actual. Actual - or True is the term that the lumber industry uses for posts that are dried before they are cut. Unlike nominal posts, which are cut when they are green and then dried, actual posts don’t shrink during drying. Green wood is wood that is still moist, and the excess moisture is sucked out of the wood during the drying process. Because of the premature cutting, nominal posts are always smaller than true posts. 6x6 deck post caps for nominal posts are a half an inch smaller on both sides.
