The AA-Series Straightener includes a range of models equipped with adjustment screws on all rollers — fully adjustable. In addition, the center-to-center (CC) distance between rollers allows them to pass freely by each other, which is especially useful for high-tensile wires where greater deformation is required. This series is further divided based on the size of the straightening rollers. The AA-Series Straightener includes a range of models equipped with adjustment screws on all rollers — fully adjustable.
