The 150 Series Single Deflection Supply Grille provides effective directional control of the air stream in one or two directions. The bars are pivoted at the face, giving a uniform, aligned appearance regardless of blade angle setting.

The hollow, air-foil grille bars are spaced on .750″ centers. Each bar is adjusted for the desired air deflection without affecting the setting of any other bar.

Available with horizontal face bars (150-H) or vertical face bars (150-V).

Specify: Series S-44 Opposed Blade Damper attached to 150 Series to make supply registers; the S-44 OBD assures even distribution of air across the grille face as well as positive volume control.
