Copper Natural Color Half Cylinder Manufacturer

The Natural Copper Single Cylinder is a compact, single-sided cylinder made from high-purity copper, ideal for securing cabinets, drawers, mailboxes and utility cabinets. Its warm copper finish will develop a unique patina over time, giving it an understated, timeless appeal that complements both traditional and contemporary furniture.
The half-cylinder design is easy to install and fits both standard mortises and European-style openings; a single set screw secures it in place without the need for extensive door modifications. The interior features a sophisticated pin-tumbler mechanism with an anti-drill plate and bobbin-style pin to protect against prying, drilling and impact. Copper has excellent corrosion and wear resistance, making it suitable for indoor and sheltered outdoor applications, and is key-only. With compact size, reliable mechanical properties and a naturally antimicrobial surface, the Natural Copper Half Cylinder combines security, durability and aesthetics to meet a variety of light-duty locking needs.
