Frequently Asked Questions

What is a cylindrical lever lock?

A cylindrical lever lock is a mechanical lock installed through a 2-1/8″ face bore and 1″ latch bore. At National Lock Supply, we carry Grade 1 and 2 lever locks that combine ADA accessibility with durability, making them more robust than tubular locks.
