Description:
- This
grille is specifically designed for direct mounting
on rigid round duct,with a curved face.

aluminium profiled construction with the advantages
of corrosion resistance and rigidity.
-
Grilles have two sets of parallel aerofoil blades
with one set mounted horizontally on the front and
other set vertically at the rear.

by grippers. Damper blade is screw operated from the
face opening.
