Atlanta Post Caps makes and sells a variety of 4x4 post caps. Our multi-functional 4x4 fence post caps will protect your wood fence posts, incorporate decorative elements to enhance the overall look and feel of your landscape, create a dramatic impact with pops of color, and allow you to enjoy your property without ever having to worry about maintenance.
Most of our 4x4 deck post caps come in two sizes: Nominal and Actual. Nominal fence post toppers fit most 3.5” x 3.5” wooden fence posts, while our Actual post caps fit wooden fence posts that are true to size - or 4” x 4”.
Our line of post caps is superior to wood fence post caps in every way. We offer 4x4 post caps that are made of ASA resin, PVC, aluminum, and handcrafted stained glass.
ASA Resin Plastic Post Caps are made in the U.S.A. They bear the Atlanta Post Caps label and are guaranteed against UV-related discoloration, fading, and warping for three years. ASA Resin wood fence post caps have a patented SNAP-CAP installation method. The Slim Profile Series, the Estate Series, and the Plateau Series are plastic post caps that are made from ASA resin.
Aluminum Fence Post Caps come with a one year warranty against fading. Our metal post caps come with two pre-drilled holes and screws that go into the holes. The color of our aluminum wood fence post caps comes from a powder coating.
