Retrofit damper with pivoting connection between deployment and operational configurations

A damper 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 comprising:

• a damper assembly that is configurable between a deployment configuration and an operational configuration, wherein:
• in the deployment configuration, the damper assembly has a reduced profile to facilitate delivery of the damper assembly through the register boot and into the forced air duct, and
• in the operational configuration, the damper assembly is configured to operate a damper blade between a closed end position in which air moving through the forced air duct is restricted from flowing past the damper assembly, and an open end position in which air moving through the forced air duct is less restricted from flowing past the damper assembly;
• a deployment member including a first end secured relative to the damper assembly and an opposing second end, wherein the first end of the deployment member is secured relative to the damper assembly such that limited rotation of the deployment member causes the deployment member to rotate relative to the damper assembly;
• and
• a coupler rotatably engaged with the damper assembly, wherein the first end of the deployment member is secured to the coupler.
