Building on BEST’s legacy of innovation, the 9K series cylindrical lock combines top-quality materials and exceptional craftsmanship into a tough, dependable, long-lasting security solution. We designed the 9K series to be low maintenance, easy to install, durable, and secure. And our range of available styles and finishes ensures that the 9K delivers design aesthetics to match a wide variety of applications.

  • Proven reliability: We tested BEST 9K locks to over 50 million cycles, proving that the series exceeds ANSI Grade 1 requirements by over fifty times. Design features like a seamless, one piece hardened steel alloy outside sleeve protect functionality and ensure more reliable performance throughout the product’s lifespan.
  • Long-term durability: Our low maintenance design with solid zinc hubs protect critical components from daily wear and tear for longer product life and lower overall cost of ownership.
  • Easy retrofit: The 9K is easy to retrofit to other door preps and competitor key systems. 
  • Quick and easy installation: The 9K’s pre-assembled design and simple instructions make installing the lock intuitive. Rose locking pin allows for quick door thickness adjustment. 
  • Simple to rekey: With easy core interchangeability, BEST 9K locks make rekeying simple.
  • Superior security: Manufactured with top-quality materials and designed for ease of use and attack resistance, the 9K series delivers security you can trust. The 9K’s vandal resistant lever includes a lost motion design allowing the lever to move 45°-60° without engaging the retractor assembly.
  • Premium aesthetics: A low profile rose design and wide variety of trims and finishes give the BEST 9K a streamlined look compatible with modern architectural trends and appropriate for any design aesthetic.
