To install the NEMEF 1739 mortise lock, ensure the door cavity is properly prepared to accommodate the lock body dimensions. Insert the lock into the mortise cutout, align it with the handle and cylinder holes, and secure it using the provided mounting points. Test the mechanism with the door open to ensure the latch and deadbolt engage correctly before final tightening of the faceplate screws.

What to consider before purchase

• Verify the backset measurement of your existing door
• Check the center-to-center distance between the handle and cylinder
• Ensure compatibility with your existing door handle and cylinder hardware

For optimal performance and longevity, it is recommended to periodically lubricate the moving parts of the lock with a suitable maintenance spray and ensure that the strike plate is correctly aligned with the latch.
