Linear Bar Grilles

Model Series 4900

49-240

The Nailor 4900 Series provides an extruded aluminum bar grille that offers beautiful styling and efficient performance.

…

Linear bar grilles offer a choice of fixed air patterns with 0°, 15° or 30° air deflection, a choice of bar widths and spacing and a wide choice of border/frame style combinations to suit most types of installation including a tapered frame used in mud in/tape and spackle applications. They are available with an optional opposed blade damper for volume control. Linear bar grilles are recommended for supply air applications in floors, window sills, and high sidewall locations. They are not generally suited to ceiling mounted supply applications (other than for directional spot heating or cooling as an air curtain) as they are not designed for horizontal projection from the face.
