How to use

Prepare the door by cutting a mortise cavity that matches common mortise lock dimensions, then insert the lock case into the cavity so the faceplate aligns with the door edge. Secure the faceplate and fix the lock body with screws through the door. Mount door handles or knobs and install escutcheons on both sides, ensuring spindle alignment for smooth latch operation. Test the latch and deadbolt movement before finalizing trim and sealants. Follow standard carpentry practices to ensure correct backset, strike plate alignment, and door gap for reliable function.

Usage recommendations

For optimal performance, use compatible handles and escutcheons sized to the lock’s spindle and backset dimensions, and verify strike plate alignment on the door frame. Regularly check and tighten mounting screws and apply a light lubricant to the latch and bolt mechanism if movement becomes stiff. For exterior use, ensure the surrounding door and frame are adequately weatherproofed to protect the mechanical components.
