What is a cylindrical lock?

Cylindrical Locks: a bored lockset whose latch or bolt locking mechanism is contained in the portion installed through the cross-bore

  • Medium, high to extra heavy duty
  • Commercial, multi-family and institutional applications
  • Pros - Heavy duty, unlimited cylinder options
  • Cons - Large rose (larger footprint on face of door), limited lever designs

Cylindrical locks with levers usually require a spring cage to lift the lever and keep it horizontal.  These spring cages lead to a bigger rose (circular, finished plate against the door) – typically around 3.5 inches in diameter.  Knob designs do not require this extra spring force and these roses usually have a diameter around 2.5 inches.
