on larger pole pigs on the outer casing there are sometimes... fins?
sticking out around the outside they attatch at the top and separate
from the main casing then run down the length and re attatch at the
bottom. does anyone know what these are? cooling tubes that work by
convection perhaps. just a little curious.
