Automatic Door Closer, Zinc Alloy Spring Door Closer, Spring for Doors with Adjustment Rod and Screws for Home, Office and Bedroom of Different Types of Doors, Round Black

The main body is made of aluminum alloy, forged from one piece. Its surface benefits from a double treatment (spray and electroplating) giving it a delicate texture. Sturdy structure provides excellent corrosion and rust resistance, effectively dampening the shock when closing the door, protecting the door and lock, making it safer and more durable. Built-in springs, wheels and sturdy lever ensure smooth and automatic closing. This system reduces the impact of the closure, eliminates slamming, prevents damage caused by knocks to the door and lock, and avoids closing forgetfulness, creating a quiet and comfortable environment in the home, hallway and garden. It is also safer for the elderly and children. Equipped with a dedicated adjustment rod, just insert it into the rotary hole to adjust the closing speed and spring tension to multiple positions. The closing force and speed are controllable, perfectly fitting doors from 20 to 40 kg. This prevents damage to the door by excessive closing force, thus improving adaptability and user comfort. Easy and universal installation: its compact structure allows installation on left or right opening doors. All necessary accessories are included (door closer, lever, screw, adjustment rod, metal guide plate, adhesive, etc.), allowing immediate installation without damaging the door. Even beginners can install it easily. Its simple and versatile design matches with different styles of home decor. Suitable for many environments and types of doors: its compact and discreet design saves space and adapts to different types of doors, including wood, metal and fire doors. It is suitable for most indoor and outdoor environments, such as homes, offices, apartments and residences. The automatic closure provides optimal comfort, combining noise reduction, safety and practicality.
