radiused elbows of diverging or converging reducing fittings. Changes in dimension shall<br />
not exceed 20° diverging angle. Elbow radii shall be at least equal to the width of the duct<br />
in the plane of the bend.<br />

shafts for positive blade control. Conceal damper linkage inside the frames and<br />
out of the air stream. The entire assembly shall not rattle or vibrate. A closed<br />
damper shall not leak more than 6 SCFM per square foot of face area when<br />
tested in accordance with AMCA Standard 500 for a damper selected at 2000<br />
FPM and tested at 4 inches of water column pressure across the face.<br />
