Copper Natural Color Half Cylinder With Knob Manufacturer

The Brass Half Cylinder with Knob is a versatile single-sided cylinder crafted from premium copper, perfect for applications such as cabinets, sliding doors, mailboxes and feature panels. Its rich copper finish develops a warm patina over time, complementing both traditional and contemporary decors. The integrated knob on the inside provides quick and ergonomic operation – simply twist to lock or unlock – while the outside allows secure access control using a matching key.

Designed to fit standard European lock patterns and mortise cutouts, the cylinder is simple to install: insert the cylinder and secure with a single set screw, without modifying the frame. The cylinder features a sophisticated pin-tumbler mechanism with an anti-drill plate and spool-style pin to protect against prying, drilling and impact. Copper’s inherent corrosion resistance and antimicrobial surface ensure long-lasting durability in both indoor and sheltered outdoor environments. Combining compact design, reliable security and tactile convenience, the Brass Half Cylinder with Knob offers an elegant, durable solution for light-duty locking needs.
