Abstract
The present invention discloses adjustable air duct sealing systems for obstructing airflow through portions of an air duct system. Such systems may include an adjustable frame assembly configured to allow changes to a perimeter of the adjustable frame assembly. Systems may also include an actuator pole connector configured to attach the adjustable air duct sealing system to an actuator pole. Systems may include two or more support arms such that each support arm connects the actuator pole connector to the adjustable frame assembly and each support arm moveably connects to the actuator pole connector to allow the support arms to adjust to changes in the perimeter of the adjustable frame assembly. Some systems also include a sheet cover configured across the adjustable frame assembly to obstruct airflow through at least a portion of the adjustable frame assembly.
