Whats the difference between Grade 1, Grade 2 and Grade 3 door hardware?
The grade of locksets is based on a series of tests done by ANSI (American National Standards Institute). These tests determine the durability and level of security protection of the lock. • Grade 1 certificationa commercial quality lock designed for heavy use in commercial and public buildings. • Grade 2 certificationthe best residential quality lock, designed and built to offer excellent security and durability for most residential applications and some light commercial applications. Grade 2 certification is highly recommended for acceptable home security. • Grade 3 certificationthe minimal acceptable quality for residential door locks. Most locksmiths recommend Grade 2 certification for all residences. Our Grade 2 Maximum Security Deadbolts and Maximum Security Handlesets offer many Grade 1 security features.
