Need to Know

- Is It the Right Fit?: Unsure if the 5/16" T-style is right for you? Check out our Seal Sample Pack to find the perfect match. We also recommend that you measure the "T" part of your existing seal with a digital caliper if you have one in order to confirm that the 5/16" T-style is correct for your garage door.

-Installation Tips: For easier installation, it's advisable to have two people. One pulls the seal through the retainer, while the other feeds the seal into it. Consider using soapy water or lubricant for a smoother process.

Exact Replacement

The information on the Garage Door Zone Website made it easy to choose the exact replacement that I needed. The old seals were cracked, shrunken, stiff, etc. so not much of a seal anymore. Replacing them was quick and easy with a shot of Silicone spray in the tracks and a helper to feed the seal. Both doors done in about 15 minutes and sealing beautifully!
