The GOODMAN 500818-MS is a medium-sized fiberglass triangle designed to direct airflow from air handling units (AHUs). Constructed with 1.5 R6 anti-microbial duct board, this assembled triangle includes UL 181 foil tape for secure attachment. It features pre-grooved sections that align perfectly with the supply outlet of the AHU, ensuring an efficient duct run split into two directions.
This product is ideal for HVAC professionals creating ductwork systems.
