Are you trying to find the fence cap or Unique designer?
Fence Cap ~~ in other words, Yamini, I'm looking for the unusual -- not the typical.
Have you checked with a place selling old architectural details pulled from demolished buildings? Sometimes you can find some really amazing things there. Otherwise, maybe check with a lumber yard that mills its own moldings, etc - they can make you whatever you like (for a price!). Good luck - I like the one pictured.
Thanks for the answers, but I'm still hoping for more ideas.
check out these offings from "deckorators"
I have used their aluminum balusters in many projects
