The GenStone Pillar Panel provides an easy-to-install solution that will give you the look of stacked stone from the box to the wall in minutes. The Pillar Panels are sold individually because the panels can be stacked on top of one another for taller posts or cut down to accommodate smaller posts. There is now no need for a mason or the hassle of wire mesh and grout since GenStone Pillar Panels simply screw to the post. The pillar panel system is designed to cover a 7.75 in. sq. post. Smaller posts can be trimmed out with furring strips to 7.75 in. x 7.75 in. sq. Color: Stratford. Material: Composite.
