APB Adjustable Post Base


On This Page

Outdoor Accents post bases secure the post or column to concrete and are perfect for outdoor projects such as pergolas, patio covers and other top-supported structures. These post bases feature decorative accents and provide ZMAX® galvanization with black powder coat for extra corrosion resistance.

APB models include a 1" standoff from the concrete to help avoid post-end rot caused by moisture. These bases accommodate lumber in both nominal and rough sizes. Optional decorative side plates are available to give the look of a four-sided post base.
