JANIA Z223 Mortise Roller Lock Narrow 72/34 Black Lacquer for Slim Stile Doors

Product Overview

The JANIA Z223 mortise lock with roller is engineered for narrow stile doors, commonly specified in residential and modern commercial buildings where slim profiles are essential. Featuring a 72/34 backset and equipped with a precision roller latch and robust strike plate, it is suitable for interior and exterior use. The durable black lacquered finish enhances corrosion resistance, supporting long-term reliability in variable indoor and sheltered outdoor conditions.

Its defining feature is the specially designed narrow profile that fits limited door stiles, eliminating challenges with installation in aluminum, steel, or glass doors where conventional mortise locks would not fit. This is particularly significant for metalwork fabricators, door OEMs, and contractors needing a lock solution compatible with slim-framed doors, making bulk procurement for renovation or new construction projects highly practical.
