I have up for sale one Wrought Openwork Spiral Sq Metal it is about 2.00" long and fits a 5/8" square shaft.  I have 20 of these available but this auction is for only one.  If you have any questions I would be happy to answer them.  I bought out a railing shop so please see my other listing as I will be listing some of the items I bought.  Buyer pays shipping I am selling this as is.  Good Luck
