An acoustical baffle system for suspension in an open plenum space comprising a plurality of parallel spaced carriers and a plurality of parallel spaced baffles suspended on and transverse to the carriers, the carriers having pairs of opposed, uniformly spaced grips on their lower faces, pairs of opposed grips being spaced along the carrier at a regular center-to-center distance greater than the spacing between a pair of opposed grips, the baffles having a relatively deep U-shaped cross-section with sides and a bottom between the sides, outwardly directed flanges at upper ends of the sides, the flanges being received in a respective pair of grips on each of a plurality of carriers.
