Abstract
What is presented is heating, ventilation, and air conditioning (HVAC) ductwork. The HVAC ductwork comprises a strip of material, which is divided into a plurality of circumferential segments by a plurality of living hinges. The living hinges allow the HVAC ductwork to unfold for transportation and storage purposes. The strip of material has both a first locking mechanism and a second locking mechanism that are adapted to interlock with each other at an interlocking site, to create the assembled HVAC ductwork.
