Seals designed to fill the gap between the bottom of a door and the floor underneath are referred to as door bottom seals.

Automatic door bottom seals are mechanically spring loaded seals that lift clear of the floor as the door opens and seal tight when the door is closed.  Some automatic door bottom seals are face mounted whilst other models are fully concealed. They operate over uneven floor surfaces and can be used with threshold plates that offer added protection against rain infiltration where doorways may be exposed to severe weather conditions.

Most door bottom seals are easily adjusted after installation without removing the door. This ensures an optimum seal is achieved and maximum performance is maintained in the event of minor building movement.

This seal is spring loaded to lift clear of the floor when the door is opened. It is acoustically designed, featuring silicon gaskets for medium temperature smoke and fire door applications. Operated automatically by pressure against the door jamb on its adjustable strike. It can also be fitted into the bottom rail of a metal door by the fabricator. Has a level adjustment to achieve an optimum seal.
