K, / Blade Thickness Introduction:, The and architectural linear bar grilles are designed to provide a clean, strong, horizontal look while offering optimum performance. The availability of a variety of frames and finishes allow the grilles to blend, compliment, or contrast with the ceiling, sidewall, sill, or floor installations. These grilles can be used on supply or return portions of heating, cooling or ventilation systems. The / series linear bar grille is an excellent choice for installation in soffit/sill applications where airflow is required to wash over a window.
