It is a non-keyed set suitable for do-it-yourself installation on both left- and right-handed doors.

It features a 3-11/16″ depth and a 45-degree keyway, facilitating reliable locking. This kit is suitable for replacing worn mortise locks when door handles remain functional. A limitation to note is that compatibility with existing hardware must be confirmed, as not all profiles align with this mortise lock.
House Guard White Handle Set with Key Cylinder
This handle set is compatible with selected sliding doors using a 3-15/16″ screw hole spacing and supports a key cylinder for added security. It requires a compatible mortise lock system and notes that strike plates or latch keepers may need to be sourced separately.

Buying Guide
What should you verify before buying?
