Fixed blade single deflection flat blade grilles for duct, ceiling & sidewall applications for most domestic and commercial projects.

Description:

Manufacture: RA Series of Return Air Grilles are constructed from high quality Aluminum (6063-T6) alloy extrusions. Frames are mitered and cleated. The frame is separated from blades by an extruded rigid PVC track that runs in to frame extrusion and become an integral part. This PVC track has parallel slots at 0 or 38 degrees to house the blades at fixed pitch of ¾”. Blades positioned at 38 degrees provide the benefit of being sight proof. Such arrangement of blade setting eliminates corrosion and vibration.

An optional opposed blade damper is attached to the return grille with positive locking spring clips, which in turn is operable, by a screwdriver from the face of the grille.

Sizes: Square & rectangular patterns are available as per chart above.
