Duct Extension Kit – 
 
Main Duct & Transition
 
When two adjacent rooms need to be 
conditioned, these kits transfer air between 
rooms (airflow distribution can be adjusted 
from 65/35 to 80/20). 
 
Refer to EDK02B (Extension Duct Kit) and 
TDK02 (Duct Extension Kit- Terminal Duct 
& Grille) for complete installation.
