How to use

Check that the chosen profile cylinder matches the lock case and that the door thickness and existing mortise cut-out accommodate a 72×60 mm case. Prepare the door by verifying alignment of strike plate and ensuring the door edge mortise is clean and sized correctly. Install the lock into the prepared mortise, fix the faceplate and strike plate, and fit the profile cylinder through the door to engage the cam with the lock mechanism. After fitting, test latch and deadbolt operation with the cylinder to confirm smooth movement and proper alignment of the strike plate.

Usage recommendations

Use a compatible profile cylinder of appropriate length to avoid cylinder overhang and ensure secure engagement; if unsure, measure door thickness and consult installation guidelines. For reliable performance, have the lock installed and adjusted by a qualified locksmith or installer and periodically check screws, cylinder fit, and strike plate alignment. Avoid forcing the cylinder or key if resistance is felt and address alignment issues promptly.
