The cylindrical latchbolts ordered here is the same one that comes with every Eternity lock, so you don't need to order one here unless you want an extra one or a replacement.
Cylindrical latchbolts are adjustable in 2 ways:
- First, they can be used with a 2-3/8" backset or a 2-3/4" backset.
- Second, the face plate can be removed so it can be used as a drive-in type latchbolt.
This latchbolt is exclusively for iButton Eternity locks, so it will not work on a Lockey lock or other brands.
