· Cast Ceramic FlatBack Elbow This is an elbow with a box back on a sweep elbow like a cementback elbow. Instead of being filled with cement, it is filled with solid cast ceramic tiles. It has a heavy resistance to wear and impact. It can be easily patched on the outside, if needed, and it is much cheaper than a ceramic tile lined elbow.
