Mortise lock for the door – what is it characterized by?
A mortise door lock – unlike a surface lock – is a lock mounted inside the door leaf. This is one of the highest levels of protection against unwanted interference inside your home or apartment. Our specialized locks guarantee you 100% protection and long-term damage-free operation in all conditions. All thanks to the fact that the locks are made of solid materials and are made in consultation with security experts, and then tested by the Laboratory of Mechanical Testing of Security Devices of the Institute of Precision Mechanics and the Central Forensic Laboratory of the Police Headquarters. The result of these demanding tests is the classification according to the PN-EN 12209: 2005 standard, as well as the certificate of the Institute of Precision Mechanics.
In addition to the security guarantee that each of our locks has, we offer products with various designs – so that you can perfectly match the appearance of the lock to the arrangement of your home or apartment. Made in accordance with the latest design trends, the locks will look elegant and timeless on your door.
