Abstract: Implementations of a tube, a baffle, and a baffle inserter are provided. In some implementations, the tube comprises one or more slots and a plurality of sidewalls that extend down from the outer surface of the tube into the tube on each elongated side of the slots. In some implementations, the baffle inserter comprises a baffle holder pivotably attached to a base at a first end where a portion of the base at the first end is slanted and a portion of the baffle holder is configured to rest on the slanted portion in a first position. In some implementations, to insert a baffle into the tube using the baffle inserter, the baffle is placed on the baffle holder in a first position and the baffle inserter is inserted inside the tube until the baffle contacts a stopper and pivots to a second position under a covered portion between two adjacent slots in the tube.
