Durable zinc alloy door closer designed for everyday home use, delivering stable and reliable automatic door closing. The compact, invisible design allows it to blend seamlessly with most modern interior styles while helping to prevent doors from slamming and improving overall safety and comfort in your living space. Simple door closing device with built‑in buffer function that slows the door as it nears the frame, reducing impact and noise. This helps protect door panels, frames, and locks from long‑term damage, while also creating a quieter environment for families with children, elderly members, or light sleepers. Mute closing device uses a smooth spring mechanism and optimized internal structure to minimize metal friction noise. When the door closes, it moves gently and quietly without sudden bangs, making it ideal for bedrooms, study rooms, offices, and other places where a peaceful, low‑noise environment is important. Invisible door automatic closing device installs discreetly on the door and frame, maintaining a clean and uncluttered appearance. The compact body is suitable for a variety of light interior doors, providing automatic closing without affecting the original door hardware style or overall decorative effect of the room. Easy‑to‑use door spring hinge with adjustable tension to fine‑tune closing speed and force according to door weight and personal preference.
