Balancing Dampers

Balancing dampers are simply manual butterfly dampers encased in a sleeve.  Each branch has a balancing damper installed. In this way, it's possible to regulate the airflow by adjusting the position of the damper.

#1 Q:   How do I determine from the wing nut position on the outside of the ductwork whether the damper is closed or open?
A:   At one end of the slot that the wingnut slides in is a pointer that indicates the position of the damper.

#2 Q:   Hello, I want to install a Balancing Damper into an existing flexible ducting line. Do I simply cut the duct and install it in-line, using a clamp or tape? Thanks.
A:   Yes, that is exactly how it is done. The damper will essentially act as a coupler.
