This Heavy Duty Soundproof, Fully Mortised Automatic Door Bottom will provide an excellent seal needed to retain your door's sound rating. The aluminum casing is fitted with a self-extinguishing and oil resistant solid neoprene insert which serves as its primary seal. Solid Neoprene has high sound control properties and is very durable. It will hold up longer over the years and should be used when applied to high frequency traffic or rough floor surfaces, such as concrete. Additionally, the interior of the aluminum anodized casing is filled with anti-squeak rubber for extra protection and to ensure smooth operation.
This product is designed to be fully mortised into a wooden door. It is great for designer doors and high end, luxury condos, since the appearance of the door is not altered. It is non-handed and can be applied directly over the floor surface or above a doorway saddle, though a saddle is recommended for higher sound control (A saddle is highly recommended also when the door bottom is sealing onto carpet). Available in aluminum mill finish and in standard stock sizes. Installation instructions and screws provided.

Custom Sizing: Custom sizes up to 60" can be purchased through our office. Please contact us at 845-388-1200.
How it Works:
This product utilizes a concealed flat mechanism which is activated by the pressure of closing the door (The brass nut at the head gets pushed in by the door jamb and that lowers the seal). The high quality neoprene rubber seal drops, filling gaps up to 1”, upon the closing of door to create a tight seal and raises up automatically when the door is opened to ensure smooth door operation. Our door bottoms have been tested through 5 million cycles and provide the same excellent quality as our surface mounted and semi-mortised automatic door bottom. For more information, see About Automatic Door Bottoms.
Automatic Door bottom can be trimmed on the field up to 3-4" depending on the size ordered, see installation guide tab.
Note: We recommend trying to keep the gap between the door and the floor at no more than 3/8" for maximum sound sealing. Larger gaps can be treated with a door saddle, or an added wood strip to the underside of the door.

Automatic Door Bottoms are available with three mounting options: Surface Mounted, Semi-Mortised and Fully Mortised. 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.
