A surface mounted application can be applied without removing the door from its hinges. For a semi-mortised, if the rabbet in the door is cut-out already, the door does not need to be removed. For a fully mortised application the door should be removed before starting. |

ANSI Codes:
The Automatic Door Bottom utilizes a concealed flat spring mechanism which is activated upon opening and closing of the door. A brass plunger is compressed when the door is closed to automatically drop the seal, starting from the hinge side first. The seal is raised when the door opens. This motion ensures a smooth drop without a drag, even on an uneven surface. It is compatible with a door saddle or against the floor. The door bottom is built from durable materials that are meant to last. It has been tested through 5 million cycles!
