Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Secure Door Access: The DOMUS Brass Double Side Key Lock Cylinder provides reliable security for doors through a keyed mechanism. The double-sided keys enable access from both sides of the door.
  • Precision Alignment: The notched cylinder design ensures accurate alignment with key pins, enhancing security and smooth operation.

Key features
