Door lock Jania Z212 72/55 mm right-hand with key and lever (MP ZW 72K55P)

Jania Z212 is a right-hand mortise door lock with a 72/55 mm backset and a keyed cylinder combined with an integrated lever handle mechanism. Intended for standard interior and exterior doors, this lock provides mechanical key locking and a spring latch operated by the lever for everyday use. The design supports installation into typical door preparations for residential and light commercial applications where a right-handed keyed lock is required.

Advantages

The lock offers secure mechanical key operation together with a lever-actuated latch for simple and intuitive door use. Its mortise construction ensures a compact fit inside the door edge, while the 72/55 mm backset dimension matches common fitting standards. The right-hand configuration and integrated lever remove the need for a separate handle set, reducing installation complexity. Materials and mechanism design focus on reliable, repeatable performance for frequent operation.

Suitable for

• Residential entrance and interior doors that require keyed security and lever operation
• Light commercial doors such as offices or small retail premises
• Replacement of existing right-hand mortise locks with 72/55 mm backset
• Situations where a combined lock and lever reduces the need for separate handle hardware

When it may not be suitable

This lock is designed specifically for right-hand doors and will not suit left-hand installations without changing door handing or selecting a left-hand model. It provides mechanical key locking and a latch but is not a high-security deadbolt intended for heavy-duty commercial security needs. For doors requiring electronic access control, multi-point locking, or higher burglary resistance ratings, consider alternative lock types.

Key specifications

• Lock type: Mortise lock with integrated lever handle
• Handing: Right-hand configuration
• Backset: 72/55 mm (measurement for latch and cylinder placement)
• Operation: Keyed cylinder for locking, lever-operated spring latch for everyday use
• Application: Interior and exterior doors for residential and light commercial use

How to use

Install the mortise lock into a suitable door cutout following the door manufacturer's or lock template dimensions for a 72/55 mm backset. Once fitted and fastened with screws, insert the keyed cylinder and secure it per installation instructions. Operate the door by turning the lever to retract the latch for normal entry and exit; use the key to lock and unlock the cylinder for secured closure. Regularly check alignment with the strike plate and ensure the cylinder and lever move smoothly.

What to consider before purchase

• Confirm your door handing is right-hand to match the lock orientation
• Verify the door preparation and backset dimensions (72/55 mm) match your door
• Ensure the intended use (residential or light commercial) aligns with a mortise lever lock's security level
• Check compatibility with your door thickness and strike plate placement

Usage recommendations

For reliable operation, install the lock in a door with proper mortise dimensions for the specified backset and use compatible strike plates. Lubricate the cylinder and latch mechanism periodically with a dry graphite or silicone-based lubricant to maintain smooth function. If increased security or electronic access is needed, evaluate complementary products such as reinforced strike plates or an upgraded locking solution.
