Ras-system DuctZipper

The RAS DuctZipper allows you to produce the highest quality duct work faster, easier, and more profitably than ever before. RAS technology and engineering have taken the seaming process from the traditional three steps down to only one.

Traditional methods rollform the receiver lock, than 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 RAS material handling system supports the blanks and 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, easy and more often than not saves a second operator!
