1) Fitment- fits many historical mortise lock pockets (in doors), but may require some work on the door.
2) Functions- we only offer a privacy, operated by a skeleton key. This lock can be used as a passage with non-keyhole trim.
3) Spindles- 8mm (3/8"-20 threads), 4" long. Solid, no swivel in middle.
4) Handing- can be field reversed by following PK 108.
