Frequently Asked Questions
What is a conventional cylinder?
A conventional cylinder is a key-operated lock core used in mortise locks, rim devices, deadbolts, and storefront hardware. At National Lock Supply, we stock mortise, rim, and deadbolt cylinders, along with IC housings and thumbturns for complete door hardware solutions.
What types of cylinders exist?
The main types are mortise cylinders (threaded for mortise locks), rim cylinders (surface-mounted), deadbolt cylinders, and interchangeable core (IC) housings that accept removable cores.
