Best 7KC 37 AB Entrance Lever Lock In Stock In Most Functions & Finishes
The BEST 7KC Series, a Grade 2 cylindrical lever set, is a popular choice for commercial office spaces, college dorms and military bases. This medium-duty cylindrical lock fits a standard door prep. And because it’s comparable to the BEST 9K lever set, it’s been specified at times for heavy-duty residential applications.
Reliable Strength
The BEST 7KC series exceeds ANSI Grade 2 requirements. Design features like through-bolt mounting studs provide strength and increased torque resistance for reliable long-term performance.
Dependable Durability
We designed the 7KC lock series for long product life in standard traffic applications, including features like a robust hub and torsion springs for extra resistance to lever sag. All 7KC internal components are treated for corrosion resistance, which ensures a longer, more reliable performance life.
Secure Design
Security is built-in to the 7KC, with features like requiring core removal before keyed levers may be removed, a snap-on inside rose concealing mounting screws and no exposed keeper holes on keyed levers.
Easy Installation and Retrofit
Each 7KC lock is pre-assembled, and its cylindrical chassis fits common door preparation, making, installation quick and easy. Retrofit and rekeying are also simple, thanks to compatibility with conventional key-in-knob cylinders. BEST interchangeable cores allow for easy rekeying without removing the levers.

Q: What is the BEST 7KC?
A: The BEST 7KC is a grade 2 cylindrical lever set that was introduced to the

lever set, however is a Grade 2 lockset, opposed to the 9K Grade 1 rating.
Q: Why is it called 7KC opposed to 7K?
A: The current BEST grade 2 cylindrical lever set series is called 7KC. Prior to
launching the 7KC cylindrical lock set in 2001, BEST offered a 7K tubular lock set. The
7K was a completely different lock with different components, door prep guidelines,
etc. The 7K product is no longer available in the market. The “C” was added to the

cylindrical 7KC.

lever. The entire installation process takes an average of 2 minutes. Since the 7KC

mind, installation for the 7KC product can be done quickly, efficiently and accurately
ultimately reducing install related errors and call-backs.
