VH / VHOB Double Deflection Supply Grille (screw up type)
Double Deflection Supply Grilles have Frame and blades that are 6063 extruded aluminum alloy with 200-R1 satin anodized finish. The frame has a typical wall thickness of .050″ and is separated from the blades with injection-molded nylon bushings. This method of assembly eliminates corrosion and vibration.

Available in clear anodized, white or a variety of custom painted colors.
