A 4-digit code cam lock with a knob and green/red indicator is an ideal choice for secure, user-friendly, and visually informative lock solutions. The green/red indicator offers a quick way for users and managers to check if the lock is secure or open, while the knob provides ease of use. This setup is popular in gyms, office lockers, and public storage areas where high visibility, easy access, and moderate security are required.

   • Simple Code Entry: Four dials are designed to turn smoothly, allowing for efficient, user-friendly access.

2. Green/Red Status Indicator:

   • Quick Visual Status Check: The green and red indicator shows the lock’s status at a glance. Green usually indicates an unlocked state, while red signals it is securely locked.
