These attributes made it the perfect woodworking tool for laying out dovetails, repeatable spacing and turning diameters. Precision made to rigid Starrett standards throughout. Features include hardened fulcrum stud, strong and flexible bow string, and centrally located leg adjustment to assure smooth action. 6” (150mm) Divider.
