The No 7755 full mortise privacy lockset for levers is based on an interior mortise lock design manufactured in New England in the early 20th century. Typically used for bedrooms, dressing rooms and bathrooms, the lock operates with a bit key. The lock features a 2-1/2″ backset and a 6″ x 1″ faceplate, which it shares with the interior passage latch set. The distance between the handle and the keyhole is 3”. The bevel of the faceplate is adjustable for thicker doors. A strike plate and wrought metal dustbox are provided. All Nanz plated and patinated finishes are available.
