The unique advantages of NCC soundproof doors

The magnetic sealing strip slowly attracts and closes the door without a "bang" sound, maintaining a quiet environment;
Lift the hinge to automatically press the door against the ground, without the need for sound insulation through the threshold;
Each door is assembled in the factory and undergoes verticality, fit, and ease of operation inspections before leaving the factory;
The separated door frame structure not only adapts to different wall thicknesses, but also has a simple and fast installation;
