Proper sealing of your door frames is a must in any serious soundproofing project, as sound waves can easily penetrate through small gaps around your door. This Adjustable Door Gasket is an easy to install and affordable head and jamb protection option. The gasket is installed on your stop molding of the door frame which allows for a tight seal.

  • As doors tend to shift and warp over time it is inevitable that eventually your gasket will lose its effectiveness and provide a compromised seal between the gasket and the door. This gasket, which is similar to our basic gasket, can be easily adjusted with a simple twist of a screwdriver, allowing you to maintain a constant tight seal.
  • Aluminum anodized casing is fitted with a high quality solid neoprene bulb with an extra lip for double seal protection. The protruding lip compensates for any natural warping or misalignment during installation and ensures a constant seal is maintained.
  • Casing is made of high quality anodized aluminum that will retain its shape and color, even through constant usage.
  • Installation screws provided. Screws are colored to blend unobtrusively with casing.

For higher sound control properties, you might want to consider our Heavy Duty Adjustable Door Gasket.

Not sure what size you need? See our installation guide on how to measure for your perimeter door gasket. If you are unsure of the exact size required, order longer than necessary as this product can easily be trimmed with a standard hacksaw.

Sizing: Door Gaskets are priced per set. Each set includes one 36" Header and two 84" Jambs.

Custom Sizing: Custom sizes up to 120" can be purchased through our office. Please call us at 845-388-1200.

To complete the perimeter of your door frame, purchase an Automatic Soundproof Door Bottom to effectively seal the gap under doors. 

Before Completing Your Purchase:

Measure your door-frame and review the product specs to ensure you will be satisfied with the way it will be installed. 

When installing, it is recommended that this product be set in a bead of caulking to ensure the integrity of the seal and prevent additional sound transmission. Alternatively you can also use a clear silicone bead along the edges.

Sound and air infiltration are very common through the gaps around the perimeter of doors. Installing a proper seal onto a door stop provides the added benefits of a door with higher sound control while it prevents energy loss, thus lowering your utility bills.

How to Measure for a Perimeter Door Gasket:

How to Measure for a Perimeter Door Gasket - Figure 1

First measure the Door Stop along the header (top) of your door from side to side (see Figure 1).

Next, measure the full length of your jamb (sides of your door), from the floor surface or doorway threshold to the top of your door header.

You can easily resize the door gasket on the field if necessary, so you might want to leave ½”- ¾” (.5” - .75”) room for error.
Make note of your required dimensions.


How to Install a Perimeter Door Gasket:



How to Install a Perimeter Door Gasket - Figure 2

First measure and test the header piece to ensure it is not too long.
If trimming is necessary, use a chop saw with a carbide blade to cut down to size.



How to Install a Perimeter Door Gasket - Figure 3

Close the door and position the header piece. Seal should simply make light contact with the door.
A fully compresses seal is not necessary and not recommended, as it will inhibit proper operation of door.

Mark screw position in the center of the hole and drill pilot holes. 

Secure header gasket with screws supplied (see Figure 3).

Test the door to ensure gasket is positioned correctly. If necessary, loosen screws, reposition gasket and tighten screws again.



How to Install a Perimeter Door Gasket - Figure 4

Repeat Step 2 above for your jamb pieces

(see Figure 4).


Once you finish installing your perimeter door gasket, enjoy the benefits of a properly sealed door for many years to come!

Comments about Door Gasket Set - Adjustable:
Combined with a auto door bottom, provides effective soundproofing for an acoustic drum studio inside our house. Make sure you measure your door carefully and read all the info on how to measure your door. Don't forget to allow for the door bottom width when submitting your measurements. Note that you can specify exact measurements for cutting- this is nice if you don't have a chop saw.
Bottom Line Yes, I would recommend this to a friend

Customers Questions and Answers

1) terry: we need this product for a door approx. 95" tall, x 3' wide. Can we get that size? If so, how much is it, and how long to get?

Trademark Soundproofing Reply: Hi Terry, Yes you can have it in that size. Takes about 5-7 days to ship out. I will have someone from sales contact you with pricing.

2) Reggie: Would I be able to get a 32" header and bottom door seal versus a 36" for DSZ870?

Trademark Soundproofing Reply:

Yes. You can trim the 36" header easily to 32" or you can call/email us and we can cut it for you (will take an extra week to ship out). Automatic door bottoms are available in 36 or 32 inch by choosing the size from the drop down. You can request custom sizing on those as well.

3) Matthew: I see this product provides two sides and one header. What do I do about the bottom of the door? DSZ870AA

Trademark Soundproofing Reply:

Hi Matthew we suggest an Automatic door bottom.

4) Ron B: are these available for 8 ft. high doors.?

Trademark Soundproofing Reply: Yes they are. Give us a call 845-388-1200 and someone will help to place that order for the custom size.

5) sree: What's the difference btwn this and the heavy duty ? Better soundproofing/STC or something else ?

Trademark Soundproofing Reply: Heavy duty one has a wider and thicker rubber seal (and a heavy duty frame which allows it to be used a the door stop on its own.

6) Brandon B: Is the only difference between this one and the heavy duty one the ability to be a door stop on its own? On the heavy duty door one of the FAQ answers says it maintains the STC of a door to within 2 points. Is that also the case with this gasket set?

Trademark Soundproofing Reply: It is also a wider and heavier neoprene seal.

7) Brandon d: How well does this gasket maintain the door's STC rating? (within how many points)

Trademark Soundproofing Reply: Within 4 points
