The Amherst Inset Demi-Top Post Cap has a simple scallop base that slides over the deck post.

As with all Acorn post caps, the Amherst is made from a single piece of cedar, or pressure-treated pine, which means there are no joints or glued pieces to come apart. In addition, the 3/8 inch inset base protects the post end grain for greater longevity. Choose from post cap sizes 3-5/8 inch, 5-5/8 inch, or 3-5/8 inch x 5-5/8 inch. AcornWood Post Caps are ready to be treated with your choice of wood oil.

Note: Post caps must be treated, or cracking/splitting/warping can occur. Wood oil should be used on all surfaces of the cap.

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