This automatic door bottom is specifically designed to create the best sound seal possible for normal sound levels. The aluminum casing is fitted with a self-extinguishing, closed-cell sponge neoprene or solid neoprene insert which serves as its primary seal. Additionally, the interior of the aluminum anodized casing is fitted with rubber for extra protection.
The mechanisim used in this ADB is of the highest quality and has been tested to over 5 million opening and closings!
The rubber used in this ADB is not cheap vinyl or EPDM rather it is long lasting neoprene.
The aluminum casing used is anodized 4 times to ensure a long lasting finish.
Sponge Neoprene vs. Solid Neoprene: Both seal materials have high sound control properties and are very durable. However, solid neoprene will hold up longer over the years and should be used when applied to high frequency traffic or rough floor surfaces, such as concrete.
This product is available as a surface mounted or semi-mortised application, as shown in the illustrations. 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 when applied over a carpeted area). Available in two anodized finishes and in standard stock sizes. Installation screws and instructions 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 spring mechanism which is activated by the pressure of closing the door (The brass nut at the head gets pushed in by the door jamb, which 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 mortised automatic door bottom. For more information, see About Automatic Door Bottoms.
Automatic Door Bottoms can be trimmed on the field up to 3-4", depending on the size ordered. See installation guide.
Note, For maximum sound contrtol, we recommend keeping the gap between door and floor at no more than 1/2". Larger gaps can be treated with a door saddle or an added wooden strip to the underside of the door.
(See our High Sound Automatic Door Bottom for use in the most demanding situations e.g. recording studios).
