Description

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 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 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

Installation Guide

Click here for a Printable Copy of How to Install an Automatic Door Bottom.

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.

STEP 1: SIZING YOUR DOOR BOTTOM:

 
  Once your door is ready for installation you need to determine the size required for your door bottom:
  • For a Surface Mounted Application: Measure the distance between the two stop moldings, or if a perimeter door gasket is applied,
    measure the distance between the two installed gaskets, then minus 1/8-1/4"” (.125”) from the total distance. That is the size needed for your door bottom.
  • For a Semi-Mortised and Fully Mortised Application: Measure your door from side to side; that is the measurement needed for your automatic door bottom.
For visual presentation see How to Measure for an Automatic Door Bottom.

Once you have determined the size needed, if necessary, trim your door bottom.
Use a chop saw or table saw to create a perfectly straight cut.

Note, Only trim opposite the actuating plunger, brass nut. (Trimming from the brass nut side will ruin your ADB).

 
How to Install an Automatic Door Bottom- Figure 1 You can trim from the edge up to one inch of the screw in the side wall of the ADB.  

STEP 2: PREP FOR ATTACHING AUTOMATIC DOOR BOTTOM:

 
How to Install an Automatic Door Bottom- Figure 3

Surface Mounted and Semi-Mortised models need to be applied to the push side of the door only (the side with the door stops-see Figure 3).
The actuating plunger needs to be applied to the hinge side of the door for all applications.

Place the automatic door bottom against the door

Once you have the automatic door bottom leveled and positioned correctly, with a pencil or marker mark
where the attachment screws need to be drilled.

 

STEP 3: ATTACHING THE AUTOMATIC DOOR BOTTOM:

 
How to Install an Automatic Door Bottom- Figure 4

To make installation easier you can drill a pilot hole which will ensure you attach the door bottom to the correctly marked spot (see Figure 4).
With the screws provided, screw in the automatic door bottom.

In some models, a plate is provided for the hinge side of the frame. This will protect the door frame from getting worn down by
the actuating plunger. If provided, attach to corresponding point on the frame.

 

STEP 4: TESTING YOUR AUTOMATIC DOOR BOTTOM:

 
How to Install an Automatic Door Bottom- Figure 1

Now that the door bottom is attached, test the door bottom by opening and closing the door to ensure there is a full seal.
If the seal does not come down far enough twist the brass nut out, if it seals too tight twist the brass nut in (see Figure 5).

 

Once you have followed through with all the instructions your Automatic Door Bottom is good to go! Enjoy years of quality sound, draft and light infiltration control with your new door bottom.
