Plastic facade grill with non-return valve 150x150 mm, connection Ø100 mm brown
This facade grille is a square outer grille with a fixed angled canopy for the extraction of air in your ventilation duct. The non-return valve prevents an opposite air flow.
The facade grille is suitable for mounting on a round ventilation duct and is made of plastic.
On the back you will see 4 screw holes. This rear part cannot be removed! To assemble the grille, remove the front of the grille. To do this, push the side of the grille slightly and remove the front. Screw the rear part and click the front part back on in the same way.
