About this product…

Porch Posts by RDI come in two different styles; turned - an elegant, timeless mold with the look of a colonial post  or square - a clean, modern, and simple mold with less maintenance. Both styles are classic, and have the option of three neutrally-toned colors; white, clay and sand. As shown in the image gallery above, these posts are a bold, and quite easy way to add a statement, value, and character to your home and curb appeal. Coming in two different sizes, these porch posts by RDI offer even more customization for the homeowner, appealing to a variety of aesthetic tastes. 

Along with aesthetic appeal, these posts are extremely structurally sound; having been tested to bear from 2500 -5000 pounds and being equipped with an aluminum structural support underneath the vinyl sleeve. Furthermore, the ‘Hurricane Lock’ features on the base of the posts keep them secure from severe weather conditions like strong winds, and eliminates ‘roof jacking’ during installation. 

Because these posts come with an aluminum structural support and a vinyl sleeve, these Porch Posts by RDI are extremely versatile; they can be used for completely new design projects, for replacing old structural posts, or for replacing old posts that already have structural support. 

All posts include recommended installation kits. Base trim sold separately
