The KEYMAN Heavy-Duty Lever Style Entry Door Lock combines robust security with exceptional flexibility for commercial environments. It meets ANSI Grade 2 standards, ensuring durability for high-traffic areas like offices, schools, and storage rooms. Its standout feature is the Small Format Interchangeable Core (SFIC), which allows for quick rekeying without replacing the entire lock—ideal for settings requiring frequent access changes. The non-handed design simplifies installation on left or right-handed doors, while the heavy-duty lever, crafted from materials like zinc alloy or stainless steel, withstands rigorous daily use. Additionally, many models are UL-listed with a 3-hour fire rating, enhancing safety in fire-rated assemblies. This lock also supports master key systems, providing scalable access control.
