Best 7KC 37 R Classroom 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.
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.
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.
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.
