C-CHANNEL
The customer may refer to the ship part, which is perpendicular to the airflow channel, using terms like C-Channel, roof trough, gutter channel, or roof covering. The C-Channel is vital for directing airflow and ensuring ventilation. Below are the specifications for the C-Channel. Note that while multiple sizes exist, many are rarely used and have not been setup or enriched.
