Tired of being overheated or overcooled because the thermostat is in another area?! 

This is an exclusive kit to block or regulate airflow in an HVAC duct quickly and easily with no permanent modifications needed to the duct.  No cutting or drilling needed, and the FlexDamper can be removed at any time. Installs in minutes!  

This kit works with existing round ducts, and can be folded or bent and inserted through a register or other small opening. They can be serviced from the register or plenum, with no need to access the exterior of a duct.  

This FlexDamper inflates as needed to restrict airflow to specific areas in your HVAC system, and then and can be easily deflated to allow full airflow when occupants choose.

Included in kit:

• 1 FlexDamper (Select the size needed based on the diameter of your duct)
• 1 FlexDamper plug
• 1 piece of FlexDamper Connect Tape for taping ends of FlexDamper together
• 3 ft. duct-rated tubing
• 1 hand inflating bulb (for orders of multiple FlexDamper Kits, we send one hand inflating bulb. When ordering multiple FlexDamper Kits, please let us know if you need more than 1 hand inflating bulb.)
