Pretty awesome video question why does it have to break away can’t figure that out
In the event of a structural failure caused by a fire, the duct will be allow to collapse without tearing the damper out of the wall or distorting it, preventing the damper from closing.
subtitle unreadable..!!!! anyway thanks for the video..!!
if your subtitle in black color would be much better
