Dr. Ammava-ckerbet Ammapa-tigte multi-point locking system for high security through bolts and swivel hooks. The locking elements are secured against counter-pressure and feature a 20 mm throw; round bolts prevent the door from being pried open and make break-in attempts more difficult. The locking mechanism is characterized by high thermal insulation and sealing, with a pleasant closing sound thanks to the plastic-coated soft lock latch.
