Description
Interior Door Lock Cylinder
This interior single-sided lock cylinder features a single-side knob design with precision-crafted copper core components. Compatible with standard interior swing door locks, it offers convenient operation and reliable locking for both installations and after-sales replacements.
Premium Construction & Durability
The internal lock cylinder and pins are precision-machined from high-quality copper, providing excellent wear resistance and rust prevention. Keys insert and remove smoothly without resistance, ensuring reliable performance even in varying humidity conditions.
The lock body features a matte silver finish with scratch-resistant and oxidation-resistant properties, maintaining a clean appearance over time. The genuine copper key has precision-machined teeth with low cross-opening rates for enhanced security.
Smooth Operation
Internal transmission mechanism provides firm, snag-free turning with clear locking feedback, capable of withstanding tens of thousands of lock cycles.
Convenient Design
Single-knob, single-opening design allows quick interior access without keys while maintaining exterior security with key-only operation.
Easy Installation
Industry-standard dimensions ensure compatibility with most conventional interior door lock bodies. No drilling or door panel modifications required.
