The 6K is a Grade 2 medium-duty cylindrical knob set.
Unlike other cylindrical knob sets that are made from weaker metals, the BEST 6K Series is constructed of steel or brass to ensure the overall strength and durability of the lock. The 6K is a commonly used lock for non-ADA compliant applications, such as govnerment and military facilities (barrack doors, base housing, etc.) as well as countries that do not require ADA compliance, such as Latin America.

Reliable knob sets for standard traffic applications.
Our 6K series offers the quality and performance you expect from BEST for standard traffic applications. BEST 6K knob sets exceed ANSI Grade 2 standards, and are built with design features that make the 6K a durable and secure choice for long-term reliability.
