Rigid arm 4" long for modular purge baffle systems.
There are two arms required when assembling your baffle system. If you are pulling your baffle system through straight pipe runs, we recommend using two rigid arms. For pipe runs with moderate bends or only one turn, we recommend using one rigid arm and one flexible arm. For pipe runs with sharp turns or multible turns, we recommend using two flexible arms.
