About this cylindrical lock
A cylindrical (bored) lock installs through a round hole in the door and a smaller hole in the edge, so it is quick to install and replace. The function sets how the inside and outside levers or knobs lock, and the ANSI/BHMA grade indicates durability: Grade 1 is the heaviest duty.
