We are a small private company that manufacturers all of our ASA resin post caps right here in the United States. We sell to property owners, contractors, and anyone who is interested in buying our deck post caps.

Our ASA resin 8x8 post caps are made of the same hard plastic that is used in cars and marine vehicles. It is an ideal material to use for making plastic caps for fence posts because of its UV and impact resistance. It will never warp, fade, or get discolored. And we’re so confident in the superior of this ASA resin over other fence post cap materials that every purchase of these plastic caps for fence posts is guaranteed for ten years against discoloring, fading and warping.

Our ASA resin deck post caps are stronger and more durable than wood because they aren’t subject to the continuous cycle of contraction and expansion that wood faces because of humidity changes. Our post caps won’t rot or get moldy, and they’ll never erode because of damage that wood-eating animals and insects inflict on it. Our plastic caps for fence posts don’t require any maintenance. And you can buy many more deck post caps from us for a fraction of what you’d have to pay for wood caps.

Our black pyramid 8x8 post caps come in two sizes: Nominal and Actual. The lumber industry uses the term “nominal” to refer to green wood or wood that is cut before it’s either dried or aged. Once the wood dries, it loses a half an inch on all sides. That’s because the once wet plank is no longer holding water.

The term “actual” refers to wood that was cut after it was dried. So pieces of wood that are sawed to the actual specification are true to the size on the label, tag, or on the board.

  • Nominal or standard 8x8 post caps will fit posts that are between 7.5” x 7.5” and 7.75” x 7.75”.
  •  Actual or true 8x8 post caps will fit posts that are 8” x 8” up to 8.5” x 8.5”.

Installation is a breeze with our fast and easy patented SNAP-CAP system. Our two-part post cap design includes a sleeve and post topper. The sleeve on these deck post caps slides about 3 inches down the post to prevent water from seeping in under the post cap. Once installed, the widest point on the post cap will be eleven -inches.

Our black pyramid 8x8 post caps are the ideal addition to any landscape, especially when you’re looking for a timeless and classic decorative element that will enhance the look of your fence while protecting your fence posts.
