Remak® Automatic Door Bottom uses a flat spring mechanism. When the door is closed, the spring is activated and the rubber gasket will be pressed tightly to the door or sill, blocking sound travelling the door slots.
The door bottom is on the inside of the door, bringing high aesthetics for the door system. As the door is closed, the plunger is compressed against the door frame, activating a concealed compressed spring mechanism. Next, the bottom of the door automatically compresses the rubber gasket to the floor, creating a tight seal that prevents penetration by sound, smoke, dust or insects. This rubber gasket will automatically raised when the door is opened to avoid scratching the floor as well as making the door easier to open or close.
Our door bottoms are designed to fit any door up to 1.2m in length. These jamb seals can be easily installed on any door system, wooden doors to steel doors. We provide 2 models of external Heavy Duty Automatic Door Bottom and 1 model installed on the inside of the door. The soundproof door bottoms mounted on the door can be easily installed without removing the door the hinges. While the door bottom on the inside of the door will require removing the door and mortise before installation.
Remak® Heavy Duty Automatic Door Bottom has an anodized surface with anti-rust and anti-oxidation properties. The door bottom is often used together with Soundprood Jamb Seals and Remak® soundproof sills as an complete solution for soundproof door system.
