ABSTRACT:
A linear air diffuser apparatus has two parallel longitudinal rails maintained spaced by two or more transverse connectors. Two or more blade-like adjustable air flow control members extend longitudinally between the connectors. Each flow control member has a planar blade end portion at each longitudinally outer end. Each connector has an upper block and a lower block with the blade end portions received between them. One or both of the blocks has on a side facing the end portions a polymeric resiliently compressible piece that is compressed between the blocks and exerts a resilient reaction urging and gripping the end portions stably between blocks so that they are not prone to vibrate.
