Straight line accuracies of .005" in six feet are possible because of Vemco''s unique system for straightening extrusions. Smooth adjustable and effortless tracking is accomplished because of specially designed track extrusions. Carriage wheels provide equal pressure at points of contact between wheels and the track regardless of board angle. Horizontal and vertical breaks control protractor movement at all times.
