Cylindrical Lever Locks Grade 1 for Demanding Environments

Grade 1 is the highest performance rating for cylindrical locks. If your doors see heavy daily traffic or need to meet commercial building codes, this is where you start.

What ANSI Grade 1 Locks Actually Mean

ANSI grade 1 locks are tested to withstand 250,000 cycles, heavy force, and repeated strikes. That rating is not just a label, it is a guarantee of long-term reliability under real conditions.

ANSI Grade 1 Door Locks for Commercial Spaces

Schools, hospitals, government buildings, office complexes, our ANSI grade 1 door locks meet the standards these environments require and hold up through years of constant use.

Grade 1 Security Door Locks When It Counts

High-traffic corridors, stairwells, and exterior entrances need hardware that will not fail. Our grade 1 security door locks are built specifically for spaces where performance cannot be compromised.

Grade 1 Commercial Door Locks at the Right Price

Top-tier hardware does not have to mean top-tier spending. Our grade 1 commercial door locks give you certified performance without the markup that often comes with commercial-grade products.
