Keyway Note: When ordering the standard L4 keyway, the cylinder comes with 2 cut keys, keyed random. When ordering any other keyway the setup is different. The cylinder is ''zero bitted'', which means it has no pins inside. The keys furnished are key blanks.
We furnish cylinders this way because customers with that have a keyway other than L4 usually have a Master Key System.
This model is the standard cylinder for Corbin Russwin's Grade 1 knob locks, the CK4200 series.
We stock the standard 6-pin version, but you can also special-order the 7-pin version. These come from the factory with a 4 week lead time (nothing comes quickly from the factory).
The cylinder is furnished with 2 keyblanks. You will need to add pins to the cylinder and cut the keys as the cylinder is ''zero bitted''. This is because it is being sold as a replacement cylinder and needs to be ''keyed'' to your application.
We can also key the cylinder at our warehouse for an additional charge.
