These are BBQ Utensil Racks from Menards, a local Big Box Store like Home Depot or Lowes. I think the racks clip on the side of a Weber. Home Depot or Lowes may also have them too.
You can buy real bacon hangers from a supplier like Butcher Packer for $5.10ea, but the hooks for $.69ea. worked just fine for me.
If you can't find "EL Cheapo Bacon Hangers" locally PM me and I'll throw a few in the mail for you?
