Product Overview

The BONAITI B-TWIN 85/50 magnetic lock with cylinder function, finished in satin chrome, is designed for interior doors, especially flush doors, in residential and commercial environments. Manufactured in Italy, it features advanced magnetic latching technology, ensuring smooth and quiet operation. Certified to EN 12209:2005 mechanical standards and rated as class 3 for durability, it is suitable for applications requiring reliable, maintenance-free hardware.

Its patented magnetic attraction system between latch and strike is the key differentiator, supporting long-lasting, wear-free performance and eliminating conventional lubrication requirements.
