DURO offers a comprehensive range of high-quality security products designed to meet the demands of both residential and commercial environments. At the core of our innovation is a proprietary 12-pin cylinder system, unique in locking technology.

Unlike conventional locks that rely on a single row of pin pairs, our modular system incorporates two opposing rows of six anti-drill pins, each meticulously crafted in varying lengths and profiles. This dual-row configuration significantly enhances resistance to picking, drilling, and forced entry, ensuring a superior level of security.

The mechanism operates exclusively with its corresponding key, which aligns a complex set of grooved pins—featuring both false and true slots—and precisely disengages forged-alloy locking bars from the lock’s internal structure. The result is a locking system that offers exceptional tamper resistance and operational reliability.

Our proprietary 12-pin design supports an extensive number of unique key combinations and is engineered for versatility across multiple formats, including profile cylinders, deadbolt cylinders, cam locks, and padlocks. This unified platform allows for scalable, keyed-alike solutions without compromising security or performance.
