Checking for size. Not all 4x4 posts are the same! Be sure to check the size.
The most common post size is 3 1/2 inches which would need the Nominal 4x4 (inside dimension is 3 5/8 inch).
If your post is 4 inches, select the Full 4x4 (inside dimension is 4 1/8 inch).
If your post is in between sizes, you might either have to use a shim and size up, or shave the sides of your post and size down on the cap.
