  1. Plain End - Stack has the same diameter from tip to bottom. It does not reduce, nor does it expand on the lower end.
  2. Expanded End- Stack expands at the end, so it will fit over the same diameter stack. Example: An 8" stack has an Expanded end that will slip over an 8" OD Diameter Elbow.
  3. Reduced Plain End- Stack reduces to 5" OD at the end. It will not slip into a 5" Elbow, unless the 5" Elbow has a 5" ID Expanded end or the Elbow is tappered at the top.
  4. Reduced Expanded End- Stack reduces to a 5" ID at the end. Example: The 5" end has an expanded end, that will slip over a 5" OD Diameter Elbow.
