If they come as links, you can hang a few without piercing the casing.
But usually I just put them on the grill grate in the PBC and cook as normal (lid on, rebar in) without flipping them. I'll let them go 45-60 minutes, but I'm usually drinking beer as I cook sausages so don't quote e me on the time
.
They come out tasty and browned.
Knockwurst, kielbasa, and Italian sausage all work great in the PBC. I also add hot dogs for the kids and a snack for me as the bigger links cook.
