Bonaiti’s design philosophy has always anticipated all needs of the market, proposing original and innovative technical solutions and ensuring the highest quality of the product.

Sophisticated IT systems allow technicians to follow every project from the beginning, up to functional tests. The test cabin looks over the operation of each lock, simulating realistic opening / closing cycles of the locks.


Research and technological development has allowed the Company to offer a complete range of products.

Thus the magnetic lock was invented, which employs an operating system entrusted to magnetic fields generated by Permanent Magnets existing in nature. The use of alternative materials to the iron, allows the silent operation. The adoption of magnetism significantly improves aesthetics and functionality.

The overall effects on the structure of the lock are obvious: a clean design that integrates with the new lines of doors. From the first model, B-ONE has progressively progressed over time to realize the B-TWO, followed by the exclusive B-FOUR, also entering the glass door sector with the B-ALEX and B-FIVE. The magnetism has also allowed to produce a lock without handle, the B NO-HA, allowing therefore to have doors without interruption of the formal architectural lines


From the widespread presence in every Italian region with the sales network of agents that reach both door manufacturers and hardware dealers, Bonaiti has passed over time to directly and indirectly distribute catalog products abroad.

Thanks to the quality of the product and the evolution of the technologies, with the Bonaiti magnetic locks, from Lake Como, it has entered the global market, conquering and managing many Countries all over the world.
