I used two L brackets that you can screw into the pillar. You will need to make sure there is a piece of wood for the bracket to screw into. You can then put a hole in the fencing and just lower it onto the L bracket.

Here is a few examples if this helps: http://www.homehaunt.net/images/2007...graveyard5.JPG and http://www.homehaunt.net/images/2007...graveyard7.JPG

I hope this helps.
