Deadbolts are typically classified into three grades: Grade 1, Grade 2, and Grade 3, according to standards set by the American National Standards Institute (ANSI). Grade 1 deadbolts offer the highest level of security and durability, making them suitable for commercial use, while Grade 2 is intended for light commercial or high-security residential use, and Grade 3 provides basic residential security.
