This shaper square is an improvement on what our competitors are selling, twice as thick, much more durable and measurements up to 35"! The Shaper's Square is used for plotting points on your blank for drawing an outline and for quick marking and measuring fins at 4" or 4.5".
Note: This product does not come with pre-cut pen marking holes. The ruler is supplied blank so users can add holes according to their own shaping preferences.
