How to use

Installation should be performed by fitting the lock body into the prepared mortise cavity in the door edge. Ensure the backset and center-to-center measurements align with your door's existing hardware holes. Once the lock body is secured, install your chosen cylinder and handle set according to the manufacturer's instructions for the specific cylinder type used. Test the latch and locking mechanism multiple times while the door is open to ensure smooth operation before final closure.

What to consider before purchase

• Verify the 85 mm center-to-center distance matches your door hardware
• Ensure the 45 mm backset is compatible with your door frame
• Purchase a compatible cylinder separately as it is not included
• Check door thickness requirements for proper handle installation

Usage recommendations

Regularly inspect the lock for debris and ensure the latch mechanism remains lubricated with a light, non-corrosive lubricant to maintain smooth performance over time.
