Description
The BEST 9K is a Grade 1 cylindrical lock engineered for demanding commercial and institutional applications where durability and security matter. Tested to over 4 million cycles, it exceeds ANSI standards and resists the wear, abuse, and lever sag that plague standard locks. Its low-maintenance design and interchangeable core reduce long-term ownership costs.
The 9K accommodates door thicknesses of 1 3/8 inch, 1 3/4 inch, and 2 1/4 inch, with multiple backset and strike options for flexible installation. BEST interchangeable cores support masterkeying and rapid rekeying. As an authorized BEST dealer, E.D. Locks offers expert guidance on keying options, core selection, and configuration.
