Berlin Modisch Single Cylinder Deadbolt Lock Slim Square - Modern High

In this review of the Berlin Modisch Single Cylinder Deadbolt Lock, the bottom line is straightforward: this is a clean, modern deadbolt for anyone who wants a low profile, square-styled lock that matches contemporary doors while offering solid keyed entry. The reviewer found it especially useful for front doors or office entrances where a simple keyed exterior and thumb-turn interior are required. Installation is quick, and the satin nickel finish gives a discreet, professional look - the main reason to buy is the combination of style and straightforward security in one compact package.

Key Features

• Slim square design: The low profile square styling complements modern and contemporary exterior and interior doors without appearing bulky.
• Single cylinder keyed entry: Keyed access from the outside with a thumb turn inside provides conventional, reliable security for front doors and offices.
• Adjustable latch: The included 60/70mm adjustable latch fits standard door preps with a 2 3/8 in to 2 3/4 in backset, reducing the need for extra modification.
• Reversible handing: Fully reversible for left and right handed doors so it can be used on nearly any exterior entrance.
• Included hardware and keys: Package contains a radius square corner striker, latch box, diagram template and two keys to get the lock working quickly.
• Satin nickel finish: The iron satin nickel finish resists glare and keeps a consistent contemporary look with door hardware.

Who It's For

This deadbolt is best for homeowners, landlords, and small business owners who want a modern-looking deadbolt that is simple to install and matches contemporary door hardware. It suits situations where a straightforward keyed entry and interior thumb turn are preferred over electronic or multi-point systems.

Those needing heavy commercial-grade longevity under continuous heavy use or a fully weatherproof, high-end commercial specification should look elsewhere; a specialized commercial lock or higher-durability model would be more appropriate in that case.
