What is the distance from the door edge to the handle center?

Can this be painted over?

What tools are required for installation?

Troubleshooting
Latch does not close fully into the strike plate
Check that the mortice cutout is deep enough and that the strike plate is perfectly aligned with the latch bolt.
The handle feels stiff or sticks when turned
Ensure the handle spindle is the correct length and that the internal door alignment isn't causing pressure on the bolt.
The latch is facing the wrong way for the door
Remove the latch bolt head, rotate it 180 degrees, and slide it back into the housing until it clicks.

Setup, Compatibility & Care
Setup Requirements
To install this lock, you will need a wood chisel, a drill, and a screwdriver. Begin by measuring the center of your door edge at the desired handle height (typically 900mm–1000mm from the floor). Use the included faceplate as a template to mark the mortice cutout.

Care & Maintenance
To maintain the black finish, wipe the faceplate and strike plate with a soft, damp cloth. Avoid using harsh chemical cleaners or abrasive scouring pads, which can damage the powder coating. If the mechanism becomes stiff over time, a small amount of dry graphite lubricant can be applied to the latch bolt to ensure smooth operation.
