ANSI Locks


ANSI is the familiar acronym for American National Standards Institute, originally formed in 1918 by five engineering societies and three U.S. government agencies.  As a private non-profit organization, ANSI promotes U.S. products, systems, processes, services and personnel throughout the world by overseeing voluntary consensus standards.  The ANSI product standards are our focus at Design Hardware, where our locksets meet and exceed ANSI accreditation.

Below you’ll find a chart of our various ANSI locks, each designed for a specific application.  To determine which of our ANSI locks you need, find your application in the “type” column.  Scan to the right to determine the ANSI lock classification number and a helpful description about how that ANSI lock functions.  We offer most of them in a Grade 1 ANSI lock, a Grade 2 ANSI lock and a Grade 3 ANSI lock.  There’s more information about each of these grades at CylindricalLock.com and Grade2Lock.com.

Each column in the chart below is our suggestive use for each application and not necessarily an ANSI requirement, but at Design Hardware, we’re not only ANSI accredited.  Our locksets meet ADA (American with Disabilities Act) requirements as well local fire codes, usage standards and more.  Regardless of the lockset you choose, our limited lifetime guarantee and dedication to quality insures your door hardware will comply with building requirements and perform flawlessly for many years.
