Supply Sidewall Grilles Product Description

Frame and blades 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.

All blades are air foil in design and individually adjustable. Standard blade spacing is 3/4" on center with 1/2" or 1" blade spacing available. At the outer edge of the frame is a specially engineered channel which retains an extruded flexible vinyl gasket that produces a positive air seal.

An optional opposed blade damper is screwdriver operated through the face of the unit, and has extruded mill finish aluminum construction and injection-molded nylon bushings separating the blades from the frame. Also available with optional plaster frame.

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

• 1. ME - 1-1/4" square contour
