BONAITI B-TWIN 85/50 Magnetic Lock Euro Cylinder Polished Gold Finish

Product Overview

The BONAITI B-TWIN 85/50 magnetic lock (polished gold) is designed for internal swing doors, particularly flush (rebate-less) models in modern residential and commercial interiors. Manufactured in Italy, it features a patented magnetic latching system that provides silent and smooth operation. EN 12209:2005 certification and highest mechanical durability class 3 underline its suitability for high-traffic installations and robust performance requirements.

What distinguishes this SKU is its upgraded magnetic mechanism and precise dimensional compatibility with previous B-TWO models, allowing straightforward replacement without new drilling. This eliminates installation risks for refurbishment contractors and streamlines door upgrades where existing B-TWO lock mortises are present. It is particularly suited to bulk procurement for interior fit-out projects targeting premium or design-focused spaces.
