Attaching small takeoff to large round duct
On my duct plan I have some 4,5 & 6 in branch airtight takeoffs that come off a 14in round trunk line that is metal.
My question is how to attach the smaller takeoffs to the large diameter trunk.
The saddle on the takeoffs is too tight of radius to attach to the trunk.
Whats the best way to do this, just use a flat takeoff?
