This is a vintage Sager French door lock set that has never been used, also known as New Old Stock. It is designed specifically for French doors and comes with a lock and handle. The lock is suitable for use in antique or vintage homes and is a great addition to any collection of architectural or hardware items. New old stock screws (brass) are wrapped up in paper. The hardware is solid brass, except for the cast iron lock set that would be inside the door. Thanks for looking!
