AIR DISTRIBUTION LINE

摘要

An air distribution line for housing may be a tube formed from an elongate sheet of plastics material. The sheet is closed to form the tube by releasable tabs engaging slots at opposing edges. These tabs may be T-tabs, the arms of which engage slots. Hence the tube may be opened for tube cleaning. The tube may be suspended from slings by non-releasable tabs such as arrowhead tabs engaging slots arranged along the length of the tube.
