N° 4428

The No 4428 drum-shaped thumbturn, often ordered alongside the No 1228 doorknob, is a confluence of minimalism and traditional form. The face of the thumb turn rises into a subtle cone and is matched by the incline on the surface of the backplate. The turnpiece typically features knurled edges and has a 1″ diameter with a backplate measuring 1-1/2″. It is available in all Nanz finishes.
