Hormann Garage Door Bottom Seal

This Hormann garage door bottom seal replacement is designed for compatible Hormann residential and commercial garage doors. The 4-inch vinyl astragal installs along the bottom of the door and uses a U-shaped T-seal profile that slides into an existing two-track bottom retainer. It provides a direct replacement option for multiple Hormann door models and is also known as the Raynor seal under part numbers 325TGY8F and 425TGY8F.

The flexible vinyl seal helps create a protective barrier between the bottom of the garage door and the floor, reducing exposure to drafts and other outside elements while helping maintain heating and cooling efficiency. The seal is sold by the foot and supplied as one continuous piece in the footage ordered.

Installation Best Practices

This Hormann garage door bottom seal slides into an existing compatible two-track bottom retainer. Before installation, inspect the retainer for bends, damage, corrosion, or debris that could interfere with installation or prevent the new seal from making consistent contact with the floor.

• Confirm that the existing retainer accepts the U-shaped T-seal profile before beginning installation.
• Measure the garage door rather than relying on the old seal, which may have changed in length over time.
• Clean dirt and debris from both retainer tracks before feeding in the replacement seal.
• Apply a small amount of dish soap to the tracks if additional lubrication is needed during installation.
• For wider garage doors, have a second person help guide the seal through the retainer.
• Center the seal and verify consistent floor contact before trimming any excess material.

For additional installation guidance, review Action Direct's garage door weather seal installation guide.
