(This picture is corrupted, but maybe able to open it separately) Glued 2" to 4" adapter to 2" pipe, and glued a reducer inside the 4" adapter to give it strength. Not sure this is required. Used hose clamp on rubber to keep outer roller from sliding off the end of the pipe. The black part the orange rubber is on is the painted end of the 1.5" galvanized pipe.
