What exactly is an ANSI grade?

The American National Standards Institute (ANSI) is a private nonprofit that administers voluntary performance standards for builder’s hardware. The purpose of ANSI grades is to help identify the quality and durability of locksets through a series of operational and security tests.


ANSI grades reflect three levels of security and durability:

  • Grade 1 certification – Highest Grade Security The strongest grade ANSI recognizes for any residential or commercial product.
  •  Grade 2 certification – Higher Residential Security Designed to offer excellent security and durability. Used mostly for residential applications and some light commercial applications.
  • Grade 3 certification – Basic Residential Security The lowest grade provided by ANSI, and the minimal acceptable quality for residential door locks.
