This 150mm-diameter white PVC spigot provides a clean sleeve through walls, panels or joinery for connecting internal ductwork to an external grille, cowl or fan. The 500mm length can be cut to suit the wall thickness and installation detail, reducing the need to join several short fittings through the penetration. Its smooth, corrosion-resistant PVC construction supports efficient airflow and straightforward cleaning, while the standard round profile connects directly to compatible 150mm duct components.
