Model DDF-RLS Series Linear Slot Registers—

Model DDF-RLS linear slot registers are extruded from aluminum with a standard satin anodized finish. They can also be ordered with a white (w) enamel finish. And like the Model DDF-R deflection registers, they too have gaskets on their margins. The air scoop with face screw adjustments is standard on registers with 1-inch-wide slots but is not available on registers with 1/2- or 3/4-inch-wide slots.

They are available in lengths from 6 inches to 48 inches in 6-inch increments and can be used on 6-inch to 30-inch diameter duct. Model DDF-R linear slot registers offer three slot widths with up to 4 slots (see table).
