Introducing BLUMOTION for doors. When used with Blum hinges, BLUMOTION for doors guarantees a smooth, silent close - no matter how hard you shut the door. Blum's soft-close insert for doors is a perfect accessory to Blum self-close hinges. These inserts are installed on the door opening side of cabinet end panels and guarantee a smooth, silent close not matter how hard the door is shut. The mechanism senses how hard the door is being closed and then adjusts resistance to keep the door from slamming. Comes with a lifetime guarantee when used with Blum hinges.
