Installation Best Practices

This garage door bottom seal installs by sliding the T-shaped attachment into an existing compatible bottom retainer. Before installation, inspect the retainer to ensure it is clean, undamaged, and capable of securely holding the new seal.

• Verify that your existing retainer accepts a 3/8" T-style seal before ordering.
• Measure the door opening instead of relying on the old seal, which may have shrunk over time.
• Clean dirt and debris from the retainer before installing the new seal.
• Apply a small amount of dish soap to the retainer channel if additional lubrication is needed during installation.
• For longer doors, having a second person help feed the seal through the retainer can make installation easier.
• Trim excess material only after the seal is fully installed and centered.
