6x6 Post Caps

Also Available On:

Whether or not you are looking for a post cap to protect your posts from mold and water rot or to decorate your landscape, we have the perfect solution for you. Since 6x6 wood posts are large enough to attract attention, it makes sense from a financial and aesthetic standpoint to protect that investment. We manufacture 6x6 post caps made of ASA plastic resin, aluminum, and some that are solar-powered lights. Our 6x6 post caps come in nominal size fitting 5.5" x 5.5" up to 5.75” x 5.75" and true size fitting 6” x 6" up to 6.25” x 6.25". 

Our True or Actual 6x6 post caps are a perfect replacement for Trex® or composite 6x6 posts.

New England 6x6 Post Cap - Pyramid Top

Our pyramid tops are a New England post cap style that fits pressure-treated 6x6 posts and rough cut and synthetic 6x6 posts. The pyramid shape prevents rain from pooling on the cap surface and serves as a deterrent to large birds.
