Atlanta Post Caps is our family owned & operated business, and we distribute millions of post caps worldwide from our headquarters in Decatur, Georgia. We're the only patented post cap on the market and are proudly manufactured in the United States!

HOW TO INSTALL YOUR POST CAP:
1 - SLIDE:
Slide the post cap base onto your post. The bottom of your post cap base is smaller than the top of the post cap, and the two cap supports should be on top side of the base.
2 - SCREW: Secure the base to the post using the 2 pre-drilled holes on each of the cap supports. We highly suggest using anti-rust screws to ensure a lasting, no-hassle attachment.
3 - PLACE: Align the top of the post cap over the secured base. This will cover the screws, so you do't be able to see them once the cap is fully installed.
4 - SNAP: Simply press and the cap will "snap" firmly into place. Your post cap is now fully installed!

WHAT ARE ATLANTA POST CAPS MADE OF? Our post caps are made from a UV-resistant, high-impact ASA resin, a material commonly used on automobiles and marine vehicles. Tough, durable ASA is what makes our post caps longer lasting than traditional wood post caps and allows them to keep their shape and color in even the harshest weather. Some styles are also available in metal!
WHAT IS THE DIFFERENCE BETWEEN NOMINAL AND ACTUAL SIZING? If you purchased lumber from the hardware store marked "4 in. x 4 in.
