High Sound Control Rated Heavy Duty Automatic Door Bottom with high quality double neoprene seal, which can fill gaps up to .75". Can be applied as surface mounted or semi mortised application. Available in two anodized finishes in standard stock sizes (Can also be trimmed on the field).

This "High Sound" automatic door bottom is designed and built to provide the ultimate in sound reduction. It features a double neoprene seal (See images above) that provide maximum sound reduction especially when used  together with our Soundproof Door Saddle.

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 also 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 415-855-4950.

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 doors 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 Bottom can be trimmed on the field up to 3-4", depending on the size ordered. See installation guide.

Note: for maximum sound control, we recommend keeping the gap between the door and floor at no more than 1/2". Larger gaps can be treated with a doorway saddle or an added wooden strip to the underside of the door.

For a complete soundproof seal, make sure you completely seal your door with our high quality Soundproof Gasketing.

Decent value for the money.
Size: 6FT*6FT, Color: Grey
Was easy to assemble. Instructions were clear. Tools were supplied. It really needs to be assembled wherever you're going to be putting it as it can come apart easily when moved. The cross bars simply fit into open ended plastic 90 degree female ends. Overall for the money and to just have some division in a room it's a good value.

Garbage
Size: 6FT*6FT, Color: Black
This product is absolute garbage! It literally took all day to put it together and if the air conditioning blows on it the wrong way than the whole thing top over and it falls apart. It’s not made of quality material and is very flimsy. The only reason I’m not returning it is because it’s too difficult to put together and I don’t wanna spend that much time trying to take it apart. Do not buy this!
