ABSTRACT:
A modular forced-air register includes two main sub-assemblies. A housing with an opening can be disposed into a hole in the floor of a room. A second sub-assembly includes a louver plate with a grid work of tri-directional vanes. Air flow is controlled by a slide grille disposed beneath the grid work and carrying an integral filter substrate secured to the slide grille. The two sub-assemblies are detachably connected to each other by an arrangement of bosses and recesses as well as a projection mounted on a flexible tang configured and disposed to engage a pocket configured in a thin wall region of the opposing sub-assembly.
