Rectangular Duct and Fittings
Often used in tight spaces, such as in walls and ceilings, rectangular duct allows you to select larger sizes without increasing duct height. Duct and fittings have interconnecting ends that lock together with brackets.

Fire-Rated Airflow Dampers
In the event of a fire, these dampers automatically stop airflow through duct. They have a fusible link that melts at 165° F, releasing a spring and causing the blades to close. Dampers meet UL 555 fire safety standards to help prevent the spread of fire for 1 ½ hours. They are undersized to fit inside duct.
