Plenum take offs are where the supply tubing connects to the plenum itself. This is an extra take off intended to be used with 1" thick, square fiberboard plenums. You will need one plenum take off per supply tubing run.
For kits accommodating multiple supply take offs, please see the SpacePak AC-TKFS-2 for (2) supply runs, or the SpacePak AC-TKFS-5 for (5) supply runs.
