RAS technology and engineering has taken the seaming process from the traditional three steps
down to only one. Traditional methods rollform then receiver lock, the rollform the flange,and
finally connect the two and close the seam. The RAS Ductzipper does all this in one smooth and
simple operation! The result is a clean joint with, extremely tight ducts, and a remarkably fast
throughput.

The system supports ducts of any size and shape to a height of 700 mm(27inches).This extremely
productive"in-line design" moves through the machine along with the duct work. After one seam
is completed,the operator simply puts the duct crosswise onto the material guidance system and
slides it back to the entry point,it's that simple and easy more than often its saves a second
operation.
