lockabl2_photo2_caseID101The main feature of this lock design is that the handle is cast with a cylindrical shaped wall, but it is then post formed to a spherical shape. If the Alloy 3 used for this casting did not have high ductility, the final shape could not be achieved and the pressure die casting process would not be possible. This lock is used for both interior and exterior applications, and the platability of Zinc Alloy 3 enables a finish with high aesthetic appeal.
