Application: The grilles are suitable for ventilation in smaller spaces (toilets, bathrooms, pantries, caravans, etc.). The back side of the grilles is equipped with a color-matching insect mesh.
Installation: Insert the threaded nails into the holes so that the split end aligns with the open hole. By placing a screwdriver into the slit and turning it left or right, we can adjust the distance of the nails. The slippage of the nails can be prevented using the rubber cap.
