Abstract
A damper assembly is configured for deployment in a forced air duct that supplies conditioned air through a register boot to a register vent secured relative to the register boot. The damper assembly includes a damper unit and a deployment strap. The deployment strap includes a first end secured relative to the damper unit and an opposing second end and has a length that is sufficient to position the damper unit in the forced air duct when the second end of the deployment strap is secured relative to the register boot. When in a deployment configuration, the damper unit has a reduced profile to facilitate deliver of the damper unit through the register boot and into the forced air duct. When in an operational configuration, the damper unit is configured to operate a damper blade between a closed position and an open position.
