The RAS duct seaming technology has been proven in more than 2000 installations around the world, As being the most ergonomically advanced design. The result is the RAS Duct Zipper. It allows you to produce the highest quality duct work faster, easier, and more profitably than ever before!
RAS technology and engineering has taken the seaming process from the traditional three steps down to only one. Traditional methods roll form then receiver lock, the roll form the flange, and finally connect the two and close the seam. The RAS Duct Zipper 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 (27 inches). 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.
