Installation Best Practices

This replacement garage door bottom seal slides into the existing Clopay single-channel bottom retainer. Before installation, inspect the retainer to ensure it is clean, undamaged, and free of debris, as a worn or damaged retainer can prevent the new seal from fitting or sealing properly.

• Verify that your garage door uses the Clopay single-channel retainer before ordering.
• Measure the door width instead of relying on the old seal, which may have shrunk over time.
• Clean dirt and debris from the retainer before sliding in the new seal.
• Use a small amount of dish soap if additional lubrication is needed during installation.
• Center the seal before trimming any excess material.
• Check that the bulb makes even contact across the entire floor after installation.

Compatibility Notice

Garage door designs can vary, and retainer shapes and sizes may have changed over time. Please double-check your existing retainer or track before ordering and contact us with photos or measurements if you need help choosing the right seal.
