Product Overview

The LOB Z9220B-22 is a universal mortise lock for use on both interior and exterior doors, supporting doors up to 200 kg in public utility buildings. Featuring a latch and bolt operation, it is suitable for left- and right-handed installation, making it versatile for commercial and institutional projects exposed to demanding usage and temperature fluctuations.
