Emtek Jefferson Double Cylinder Entry Handle 4425

Double Cylinder: locks are keyed on both the exterior and interior portions and add an extra layer of security to certain environments. An example would be to use a double cylinder where there's glass in close proximity to the handle, thus disallowing an intruder from unlocking the door from the inside should they break through.
