North Carolina Correctional Officer State Practice Exam

Which type of padlock is commonly used in prisons?

1. Combination lock

2. Master lock

3. Electronic lock

4. Digital keypad lock

The correct answer is: Master lock

The type of padlock commonly used in prisons is the Master lock. These locks are favored for their reliability and sturdiness, essential characteristics in a correctional facility where security is paramount. Master locks often feature a durable construction that can withstand tampering and the wear associated with high-security environments. While combination locks are often reliable, they can be more complex to manage in a high-stress situation since they require specific codes, and there's the potential for forgetting these combinations. Electronic locks and digital keypad locks provide advanced features, but they may be less common in traditional prison settings due to the need for power sources, potential for malfunction, and increased maintenance requirements. In comparison, the simplicity and mechanical reliability of Master locks make them a preferred choice in such facilities.
