Eggcrate soffit grilles provide a high-free-area termination for passive air intake or exhaust through soffits, eaves and underfloor spaces. Manufactured from UV-stabilised plastic, the grille is designed for low airflow resistance and long-term exterior use. The removable eggcrate core allows easy access for cleaning and maintenance, while the integrated insect mesh helps prevent pests and debris from entering the duct system without significantly restricting airflow.
