Combining quality, aesthetics, and durability. 
Built from the quality materials and workmanship that characterize BEST locks, 
the 6K series comes in a range of finishes and options to fit modern architectural 
trends and provide long-lasting value.
BEST 6K  
•  High quality. We use top quality materials 
and construction to manufacture 6K locks. 
External components are designed for 
premium aesthetics and security, while internal 
components are treated for corrosion resistance 
to ensure long product life.
•  Proven reliability. BEST 6K knob sets exceed 
ANSI Grade 2 requirements for security and 
reliability. Design features like the 6K’s keyed knob 
design and strong retractor springs provide better 
functionality throughout the life of the lock. 
•  Enhanced security. We designed the 6K series 
to provide security and peace of mind. Cores 
must be removed before keyed knobs to deter 
break-in attempts, and a snap-on inside rose 
with no exposed screws helps to deter attacks. 
•  Convenient installation. Install 6K knob sets 
quickly thanks to design features that make 
installation, retrofit, and maintenance easy. The 
6K series fits standard door preps, a threaded 
outside rose allows quick door thickness 
adjustment, and the lock installs easily with 
only two screws. BEST 6K series locks are field 
reversible without removing the keyed knob, and 
retrofit is simple with BEST interchangeable cores. 
•  Greater flexibility. The 6K series fits a wider 
range of applications and offers finish options  
to match any aesthetic. Each 6K lock set  
comes in four different backsets and seven 
different finishes.
