Understanding ANSI Grades for Locks

The American National Standards Institute (ANSI) and the Builders Hardware Manufacturers Association (BHMA) have developed a grading system to categorize the security and durability of locks, ranging from Grade 1 to Grade 3. These grades are based on rigorous testing by ANSI to determine the durability and level of security protection each lock provides.

• Grade 1 Certification: This is the highest grade, offering commercial-quality security designed for heavy use in commercial and public buildings. Grade 1 locks provide the most robust protection, making them ideal for high-security residential settings as well.
• Grade 2 Certification: Known as the best residential quality lock, Grade 2 offers excellent security and durability for most residential applications and some light commercial settings. It is highly recommended for acceptable home security and provides a balance between security and cost.
• Grade 3 Certification: As the minimal acceptable quality for residential door locks, Grade 3 is designed for basic residential security and light-duty applications. Most locksmiths recommend opting for Grade 2 certification for all residences to ensure adequate protection.

Understanding these ANSI grades helps consumers choose the right lock for their specific needs, ensuring optimal security and durability.
