Engel Button Punch Snap Lock Roll Formers form a two piece seam that greatly simplifies ductwork assembly. The male seam is a button, the female seam is a lock and the two snap together for a flush corner. These machines are available in eight forming station machines. Not only do these locks assemble twice as fast as traditional methods, but because the two pieces nest, they are easier to transport too. Available models:
