The 550 LTA Series Long Throw Return Air Grille is styled to match the 150 and 250 Supply Grilles. The face bars are non-adjustable and available in either a horizontal position (H) or vertical position (V).

The same hollow air-foil bars used on the supply grilles are used on the return air grilles.

Specify: Series S-44 Opposed Blade Damper to make return register. The S-44 OBD assures even distribution of air across the grille face, as well as positive volume control.
