Sometimes deck and porch posts aren’t your standard 4x4 wood post. Maybe one post is slightly bigger. Or you're using a post sleeve that adds extra thickness. This Deckorators® post cap can fit those non-uniform posts.
It comes with 3 inserts that go inside the base (completely hidden) to fit posts ranging in size from 3-1/2 in. x 3-1/2 in. to 4-5/8 in. x 4-5/8 in. Top and base are the same color for a clean look. Compatible with wood, vinyl, or composite posts.
