Photos of the Portland Furnaces.

This is the element protruding thru a soft brick. The shank is 7/16th inch diameter and fifteen inches long.. The outer two inches is the connection section for the electric strap. The next nine inches is in the brick and then it enters the crown. the very last half inch of the shank has to be inside of the furnace.. The thinner port, which isn't in this picture is the heating portion. Jons was 18 inch, Steve's was 12 inch.
