ANSI (American National Standards Institute) grades 2 and 3 refer to different levels of security and durability for locks and hardware. Grade 2 offers a medium level of security and is commonly used in residential and light commercial applications, while Grade 3 provides a basic level of security, typically suitable for residential use. Grade 2 locks generally undergo more rigorous testing and offer better performance and longevity compared to Grade 3.
