The 250 Series Double Deflection Supply Grille provides effective directional control of the air stream in one, two, three or four directions. Each bank of blades is pivoted at the front which gives a uniform appearance regardless of blade angle setting.
The hollow air-foil grille blades are spaced on .750″ centers. Each blade is adjusted for the desired air deflection without affecting the setting of any other blade.
Available with horizontal face blades (250-H) or vertical face blades (250-V).
Specify: Series S-44 Opposed Blade Damper attached to 250 Series to make supply registers. The S-44 OBD assures even distribution of air across the grille face as well as positive volume control.
