All Aurora Aluminim Post Caps have the ability to fit on different sized posts.  Many Aurora post caps come standard with the Base Converter already sized for your post, however with certain combinations, the Base Converter must be purchased in addition to the standard post cap in order to properly fit your post.

If the Aurora Post Cap size drop down does not show your post size, the cap can be still be ordered in the "wrong" size.  Simply order the proper Base Converter for your post and the wrong base can be removed and the new Base Converter will take its place.  Converters are attached with machine screws.

Note however that Base Converters are available in many colors, but not all size/color combinations are available.

All Aurora Aluminum Post Caps use either a 4x4 top and a Base Converter or a 6x6 top and a Base Converter.   All caps come with 1 base, which can be swapped out.  

4x4 tops include: 3-1/2", 4", 4-3/8", 4-5/8", and 5" post caps.  If you have one of these caps, you can convert to any other size in this 4x4 list.

6x6 tops include: 5-1/2", 6", and 6-1/2" post caps. If you have one of these caps, you can convert to any other size in this 6x6 list.

The converstion bases appear slighlty different depending on the target size:
