• 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.
For a durable, reliable standard-duty
knob set that builds on decades of
expertise and innovation, choose
the BEST 6K series.
