The Boulevard is a flat post top cap with a 3/8 inch inset that slides over the deck post and protects the end grain.

As with all Acorn post caps, the Boulevard is made from a single piece of ipe, cedar, or pressure-treated pine. This eliminates any joints or glued pieces that can come apart. Additionally, the 3/8 inch inset base protects the post end grain for greater longevity. Choose from post cap sizes 3-5/8 inch or 5-5/8 inch. Acorn Wood Post Caps are ready to be treated with your choice of wood oil. Note: post caps must be treated, or cracking/splitting can occur. Wood oil should be used on all surfaces of the cap, inside and out.

Unsure about your size? Measure your posts carefully and use our Post Cap Diagram to understand critical dimensions and ensure a proper fit.
