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. 

Not sure what size you need? See How to Measure for an Automatic Door Bottom.

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.

Comments about Heavy Duty High Sound Automatic Door Bottom:
I would never buy from this company again!! Bought their door sweep & ripped the outer rubber. Which is very soft & easy to rip? I called 2 times & asked if I could buy that rubber. All I got was I do not know. They said I will look into it & I never hear back from them.

Comments about Heavy Duty High Sound Automatic Door Bottom:
We needed a solution to reduce noise and block odors coming in from the hallway into our apartment through the gaps underneath and around the entrance door. The heavy duty door bottom, together with the gaskets we installed, solved the problem. Very easy to install, and very cost effective. Great customer service, too. (We needed some help to to pick the right product and the right sizes.)

Customers Questions and Answers

1) Natasha: I would like to order the heavy duty high sound automatic door bottom, but I would like to order it in a 31" width. Is that possible?

Trademark Soundproofing Reply: Hi Natasha. Yes that is possible it would would just take 7-10 business days. You can order the 32" and in the customer notes on the checkout page just write that you would like it to be custom cut to 31" and are aware that it would take a few extra days to ship. There is no extra charge for this. If you would like you can also give us a call to place the order over the phone. 845-388-1200. Thank You

2) Ken M: Can you company cut(367AA6) this to the exact size that I need?

Trademark Soundproofing Reply: Hi Ken, Yes you can order a custom size. It would take 5-10 business days to ship. Just send us an email or give us a call.

3) Linda J: Hello, Does it matter on which side of the door the door bottom is installed? I'd like to install it on the side of the door that swings in.

Trademark Soundproofing Reply: Hi Linda. Yes it does. A surface mounted ADB can only be installed on the push side of the door between the door jambs.

4) Linda J: Sorry to be dense - is the push side meaning push to open or push to close?

Trademark Soundproofing Reply: Push to open

5) TERRY M: Not realizing I could order Automatic Door Bottom cut to size, I am going to have to size the unit myself. I am concerned that when the saw blade hits the rubber seal, it is going to tear/damage it. Should the seal be removed before making the cut and then trimmed to size? If so, how do I remove the seal? If not, how do I prevent the seal being damaged?

Trademark Soundproofing Reply: On this particular model we do not recommend removing the rubber. If you are using a strong circular saw blade you should have no issues cutting through the rubber without it tearing. You can also push the bottom out and cut the rubber with a utility knife first.

6) sree: what's the difference between this and the basic ? Specifically any difference in STC numbers ? What improvement if any will a threshold (in addition to the ADB) add for a wooden floor ? thx

Trademark Soundproofing Reply: It is a wider and thicker seal. This one also has a double neoprene which will stop anything from going over the top of the seal. A threshold allows for a better seal if the floor is not perfectly smooth.

7) Steve J: Can the neoprene seal be replaced if it is damaged or degraded, or does the entire need to be replaced?

Trademark Soundproofing Reply: It can. However on the high sound ADB it is difficult due to the 2nd layer of neoprene that is attached inside the housing. On the standard heavy duty ADB it is very simple to replace.

8) Tom: Can he automatic door seals be custom cut with a chop saw? And does the seal have to be removed during cutting and ct separately?

Trademark Soundproofing Reply: Yes they can be trimmed with a chop saw (Side opposite the brass nut - up to the sidewall screw). You can cut the seal at the same time. On the high sound we do not recommend that you try to remove the seal as it would be extremely difficult to place it back in.

9) Greg: Does this product "Heavy Duty High Sound Automatic Door Bottom" come with the plunger plate?

Trademark Soundproofing Reply: Yes it does.

10) Mauricio: Hello, I'm interested in the Heavy Duty High Sound Automatic Door Bottom, but I have a question: Can I trim the 32" length to 28"? Thank you!

Trademark Soundproofing Reply: Yes you can. If you would like you can request a custom cut from the office and we will send it to you at 28". It will just take about 10 business days to ship.

11) Brian R: Can this product be used to seal the bottom of an exterior door for insulation? I am looking to replace a mortised door drop that is installed in a very old door. I would like to know how this product would work in terms of it thermal transfer and ability to block air flow. Thanks, Brian.

Trademark Soundproofing Reply: Hi Brian. Yes. This would work perfectly for that. Try to ensure that the gap ins not greater that 3/4 of an inch.

12) jack: Can I get screws that match the color of the ADB - dark bronze?

Trademark Soundproofing Reply: Hi Jack. The screws that come with this ADB match the ADB.

13) Scott: Hi- The gap under my door is 1-1/8". May I simply mount the unit 3/8" lower than the bottom of the door to achieve a 3/4" gap?

Trademark Soundproofing Reply: You can. However I would recommend that you add a half inch wood furring to the bottom of your door and mount it that way.

14) Brandon der Bl├Ątter: How well does this product maintain the doors STC rating? (within how many points)

Trademark Soundproofing Reply: 2 Points.
