Size: 4x6 Fence Post Caps
Checking for size. Not all 4x6 posts are the same! Be sure to check the size.
The most common post size is 3 1/2 x 5 1/2 which would
need the Nominal 4x4 (inside dimension is 3 5/8 x 5 5/8 inch).
If your post is a true 4 inch x 6 inch, select the Full 4x6 (inside dimension is 4 1/8 x 6 1/8 inch).
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.
Custom post caps: Only our flat caps can be customized. A custom fee of $20 per size change is charged, plus the cost of the cap.
