Tjernlund Products VH1-4 Aluminum Hood for Sidewall Vent 4"

The Tjernlund Products VH1-4 Aluminum-Hood for Sidewall Vent is a 4" diameter venting part that provides efficient air exhaust in HVAC systems. It terminates sidewall venting, which is commonly used with furnaces, water heaters, and boilers. The sleek hood design keeps backdrafts out and protects from rain, debris and pests. It is better for residential or light commercial use because of proper airflow while protecting equipment and structure. This improves system performance by keeping ventilation optimal and extending the life of connected units safely and reliably.
