Mortise Rim Lock LOB Madona 1490Z-297-BB 30 backset, keyed cylinder

LOB Madona 1490Z-297-BB is a surface-mounted rim/mortise lock designed to secure wooden and metal doors. The mechanism combines a latch and a deadbolt operated by a keyed cylinder, with a 30 mm backset that positions the cylinder at a standard distance from the door edge. The lock is intended for residential and light commercial installations where a robust, surface-mounted solution is preferred over fully recessed mortise locks.

Advantages

The lock provides combined latch and deadbolt functionality in a single unit, enabling straightforward locking and one-handed operation with a key. The keyed cylinder offers controlled access while the surface-mounted design simplifies installation on existing doors without major cutting or frame modification. Built for frequent use in everyday environments, the product balances mechanical security with ease of retrofit installation.

Suitable for

• External and internal wooden doors in homes and apartments
• Metal doors in light commercial or utility spaces
• Doors that require surface-mounted locking where recessed mortise installation is impractical
• Upgrades or replacements for existing rim locks

Key specifications

• Lock type: rim/mortise surface-mounted lock with separate latch and deadbolt functions
• Backset: 30 mm
• Operation: keyed cylinder for locking/unlocking
• Suitable door materials: wood and metal
• Application: residential and light commercial use

How to use

Install the lock on the door surface following the door manufacturer’s recommendations for placement at a comfortable height. Align the strike plate on the frame so the latch and deadbolt engage smoothly. Use the provided keyed cylinder to lock and unlock the deadbolt; the latch operates when the door is closed and can typically be retracted with a handle or thumbturn if fitted. Test operation several times after installation to ensure correct alignment and smooth movement of latch and deadbolt.

Usage recommendations

For reliable performance, ensure the door and frame are solid and properly aligned before installing the rim lock. Periodically lubricate the cylinder and moving parts with a dry graphite or silicone-based lubricant to maintain smooth key action and bolt movement. For exterior installations, check weather sealing around the door and consider corrosion-resistant maintenance if the lock is exposed to harsh conditions.
