UNDOR protects your cables by taking the weight of your garage door. The result is roughly a 1 inch gap between your door and the floor. We fill in that gap with a new, taller garage door seal.

Door seals are measured by their flat width. During installation they get folded in half like a taco. So when shopping you’ll see sizing such as 3″ wide, 4″ wide, etc. That is not the height of the seal once installed, it is the width of the seal when laid flat.

When you are shopping for a new garage door seal, it needs to be tall enough to fill in a 1 inch gap. We have found that a 4″ wide door seal is usually enough to do the job, but some garages may need a wider seal, such as a 6″ seal, to fill in the gap.

Not all garage floors are the same, and some have significant ruts in them from years of use. This is an example of where an even taller garage door seal may be needed. Please do some investigating for your specific application to ensure you get the right seal for your unique garage.

Let’s find the right seal for your garage door. It’s important to know that there is no universal seal for all garage doors. There are many types of garage door seal types out there, and getting the correct one for your door will mean the difference between a simple install and a frustrating experience. 

The most common door seal type in North America is the T-Style Bulb seal, which uses T shaped ends to slide into the channel on the bottom of your door. Many major door manufactures choose this seal type. There are also J type door seals, bead style seals, and many others. You can find out which seal type your door takes by looking up the make and model of your door. You can generally find this information by looking at the inside of your door for a sticker placed there by the manufacturer. 

If you can’t find the make and model of your door, simply look at the ends of the seal track and try to see what kind of seal is currently installed.

Some Notable Exceptions

Wayne Dalton Doors take a special kind of seal. It looks similar to a T style, but is has a tear drop shape. We have links below to some online retailers that carry a 4″ Wayne Dalton specific door seal.

Wooden doors can sometimes present a challenge. Wooden doors can come with a simple foam seal that is nailed to the bottom of the door. This will not work with UNDOR, and you’ll likely need to install a track to the bottom of your door to accommodate a T style bulb seal. 

Waterproofing Thresholds present an interesting situation. If you rely on a waterproofing threshold to keep water out of your garage, please note that UNDOR is not a water proofing product and offers no protection against standing water. You could, in theory, cut your threshold to fit UNDOR at each end, and simply continue installation as normal. In this case, you would lose water protection where UNDOR is installed.

There is a chance you might not be able to locate a seal for your door. Some doors are quite old and may have a proprietary seal that is no longer manufactured. You may have a wooden door that doesn’t have a conventional rubber seal. That’s ok. There are still options available for you.

There are kits available that include an aluminum track that accepts a standard t-style bulb seal. These tracks are easy to attach to the bottom of your door, and then you simply slide in a new rubber seal. Here is a video explaining how to do it, and what’s involved.

We have links in the next tab of where you can buy these aluminum track kits.

It is unlikely that you will find 4″ garage door seals at your local hardware store, Home Depot or Lowes. We have found that purchasing a seal from a dedicated online source is far easier and the selection is much better. Please see some online stores below that carry a wide variety of garage door seals, track kits, and harder to find seals including 4″ Wayne Dalton seals.
