BONAITI B-TWIN 90/50 Magnetic Lock Satin Gold EN 12209 Class 3 Keyed Interior

Product Overview

The BONAITI B-TWIN 90/50 magnetic lock in satin gold is designed for interior doors, especially non-rebated models in residential and commercial settings. Manufactured in Italy, it utilizes advanced magnetic technology for silent and effortless latching. Certified to EN 12209:2005 with the highest mechanical durability (class 3), it requires no lubrication and delivers consistent performance through a patented magnetic attraction system between latch and strike.

Its compatibility with both left- and right-hand doors, along with matching B-TWO lock dimensions, eliminates the need for additional drilling during retrofit installations. This feature notably reduces replacement complexity and installation time, making it particularly suitable for facility maintenance teams and bulk refurbishment projects seeking a low-interruption hardware upgrade.
