Cornermatic PLUS® InGround

Machine Description

Cornermatic PLUS®  IG

The Cornermatic IG, in ground, accommodates production of the largest ducts and fittings. With the Cornermatic Plus technology situated in the ground, fabricators have more room to maneuver and insert the corners to their duct in an easy and efficient manner. Controls, utility connections, and lifting hooks are easily accessible on the top of the machine for setting project parameters on the fly.
