Cable seal features compact air plenum grommet
October 6, 2008—PDU Cables has expanded its Air Guard Cable Seal product line with Air Block, a 2-piece heavy-duty, compact floor grommet. Air Block is designed to eliminate air leakage in under-floor installations and to conserve energy. The grommet splits into two sections, simplifying installation--cables don't have to be fished through the grommet.
