The Trough Blank Off (TBO) can be used to create a continuous-grille look with underfloor plenums and terminals such as the Linear Ducted Plenum (LDP), Linear Bar Terminal (LBT), and Perimeter Natural Convection Terminal (PNT). Quickly removable endcaps on the plenums and terminals make installation of the TBO very simple. The TBO can be used in flanged and flangeless applications, and can be ordered with pedestal brackets.
