The Pelham Thin Flat Top Post Cap from Acorn sits directly on top of the deck post and has a soft rounded edge.

The Pelham Thin Flat Top Post Cap sits ON TOP of the post and NOT OVER the post.

As with all Acorn post caps, the Pelham is made from a single piece of wood, which means there are no joints or glued pieces to come apart. Acorn Wood 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.
