Servo Door Frame Technology
Say goodbye to customizations and long waiting times. Designed in accordance with Lu Ban ruler door specifications and incorporating Soundbox's patented servo-type telescopic door frame technology, it adapts to uneven wall thicknesses, allowing free cutting for walls ranging from 120mm to 240mm in thickness.
Quiet Lock
The quiet lock simplifies the complex traditional hardware structure, replacing mechanical components with a non-transmission module. The magnetic lock tongue senses and retracts, avoiding mechanical contact with the door frame.
This ensures a noiseless locking and unlocking process, making the door both soundproof and silent.
