Wall cap for six-inch round duct

The Broan 843BL wall cap fits a six-inch round duct and provides a weather-resistant exterior termination for bathroom ventilation systems. Its black finish blends with darker siding or trim while the durable construction withstands outdoor exposure. This accessory completes the duct run from an interior fan to the outside of the building.

Suits installers finishing a six-inch duct run

Homeowners or contractors completing a bathroom exhaust installation with six-inch round ductwork will find this cap matches the required diameter. It is not intended for rectangular duct connections, smaller or larger round sizes, or interior-only mounting where an exterior wall termination is not needed.

Six-inch round duct compatibility decides fit

The single specification that determines whether this part works is the six-inch round duct size; the cap is engineered only for that diameter. If the project uses any other duct shape or dimension, a different wall cap must be selected to ensure proper airflow and sealing.
