Universal ISEO mortise lock with 90 mm center distance and cylinder for secure locking of interior and entrance doors. The design without latch support is intended exclusively for lever–lever hardware, ensuring reliable operation and long service life. Thanks to the mortise depth of 65 mm, it is easy to install in standard door leaves.
The ISEO mortise lock is a quality solution for doors where handle operation from both sides is required. The 90/40/20/230 model is designed without latch support operated by the cylinder, and is therefore suitable exclusively for sets with lever–lever hardware. It offers precise alignment in the frame, quiet operation, and durable mechanics for everyday use.
Installation is simple thanks to the 65 mm mortise depth and standardized dimensions. The lock is ideal for renovations and new builds where safety, functionality, and reliability are key.
