BONAITI B-TWIN 90/50 Magnetic Lock WC Privacy Universal Handing Polished Gold EN 12209

Product Overview

The BONAITI B-TWIN 90/50 magnetic lock with WC privacy function is an Italian-made door lock designed for interior non-rebated doors. It utilizes advanced magnetic technology to ensure quiet, smooth operation and is certified according to EN 12209:2005 standard, achieving the highest mechanical durability class (class 3). The lock body is constructed from steel and glass fiber reinforced polymer for longevity and stable performance in frequent-use environments such as residential apartments or commercial interiors.

What distinguishes this specific SKU is its universal handing, allowing installation on both left- and right-handed doors without modification. This eliminates procurement errors and reduces the need for different stock-keeping units, which benefits distributors and large-scale installers managing diverse door schedules. It is particularly suitable for bulk supply in residential developments, hotels, and office fit-outs requiring tactile, quiet, and contemporary access solutions.
