Weather Cowls for Express Duct Clipped Ducting

These ducting cowls are part of the Express Duct clipped ducting range and connect using the same clipped connection style as other Express Duct components.

They are used as an external end component where a duct run needs a weather cowl fitted to the outlet. The cowl shape helps reduce the chance of rain, snow and birds entering the ductwork, while keeping the connection format consistent with the wider Express Duct system.
