A HVAC branch line includes a boot, flexible duct, and integral connection therebetween. The boot can be configured to pre-hold fasteners to facilitate field installation. The branch line can also include one or more straps or other another structure, which are used to support the branch line, and optionally compress the duct before, during or after installation. Since the duct and boot are integrally connected, a field connection between the two is unnecessary and the duct can be easily supported during installation of the branch line.
