    This regular duty automatic door bottom lowers a nylon brush seal when the door is closed to prevent infiltration of light, drafts, dust and insects. The high quality mechanism requires low closing force and has a smooth action.

    This is fitted with a nylon brush seal. The brush conforms well to surface irregularities and can be used on uneven surfaces, such as tiles or a carpeted area. A metal bar prevents bristles from lowering too much and crimping. Fills gaps up to .75".

    This automatic door bottom can be surface mounted or semi-mortised applied to the face of the door.

    Handing: This door bottom is handed and is not reversible. Not sure what handing is required for your door? See How to Determine Handing / Swing of Door.

    Installation: Installation instructions, screws and end plates provided. Screws are colored to coordinate with casing.

    Please note, images are for illustrative purposes only. They are not actual photos. Therefore, actual colors may vary slightly and size may be enlarged to show detail. See product specs for exact measurements.

    How It Works

    The high quality automatic mechanism consists of an aluminum case which surrounds a moveable drop-bar seal. The drop-bar seal is actuated by a plunger which contacts the door jamb as the door is closing, forcing the drop-bar seal down against the floor / threshold. The plunger requires low "Feather Touch" closing force to actuate the drop-bar seal. The plunger causes the seal to always actuate on the hinge side first, which prevents the seal from skidding along the floor/threshold while the door is being closed. Door hang-up will not occur!
