4X6 Post Caps

Actual vs Nominal

4x6 Fence Post Caps

Our 4x6 fence post caps are designed to protect your fence or deck posts and be attractive at the same time.  These post caps are made from a marine grade plastic resin, and come with our 10 Year Guarantee. Our 4x6 caps fit nominal posts measuring 3.5" x 5.5" up to 3.75" up to 5.75".

They are made of the same ASA resin as the other post caps in our SNAP-Cap line. ASA resin was originally developed for use in auto and marine vehicles. We use the material to create a line of fence post caps that we believe are superior to comparable wood products in every way. The material gives our caps an incredible weather-ability while being surprisingly light weight.

  • We guarantee all of our ASA resin post caps against discoloration, fading, and warping for ten years.
  • Our ASA resin fence post caps are UV and impact resistant. They will withstand the rigors of any climate throughout every season of the year.
  • We make all of our SNAP-Cap post caps in the USA.
  • Our fence post caps are free from the moisture problems that cause wood to contract and expand.
  • Our ASA resin fence post caps won’t chip, erode or decay because of weather-related, gnawing animal, or insect damage.
  • We sell our products directly to consumers and businesses - whether you’re buying a few post caps or buying them in bulk.

All of the 4x6 post caps have a patented SNAP-CAP installation, a feature that makes it easy for you to install the caps without professional assistance. Once they’re installed, you won’t have to worry about any of the maintenance that’s associated with wooden post caps. Our fence post toppers cost far less than wooden caps.
