Commercial Roll Up Door Bottom Seal

This commercial roll up door bottom seal is designed for rolling steel doors equipped with double-angle bottom bars. The flexible seal clamps to the bottom of the door and forms a bulb-style barrier along the floor. It is intended for commercial and industrial rolling doors, including single-track garage doors, storage unit doors, and similar applications.

Made from tough, flexible vinyl, this roll up door bottom seal helps improve heat retention while reducing drafts, moisture, dirt, leaves, and pest intrusion. The 1.5-inch bulb-style flap conforms against the floor as the door closes. Order the seal by the foot for a custom continuous length or select a 100-foot reel for larger projects and multiple-door installations.

Installation Best Practices

This commercial garage door bottom seal clamps into the double-angle bottom bar of the rolling steel door. Before installation, inspect the existing bottom bar and mounting surfaces for damage, rust, debris, or distortion that could prevent the new seal from being secured evenly.

• Confirm that the door has a compatible double-angle bottom bar before removing the existing seal.
• Measure the actual door width rather than relying on the old seal, which may have stretched, shrunk, or been trimmed incorrectly.
• Clean dirt, rust, and remaining seal material from the bottom-bar surfaces before positioning the replacement.
• Keep the vinyl centered and evenly tensioned across the full width of the door.
• Secure the bottom-bar hardware evenly so the seal remains in position during door operation.
• Trim excess material only after the seal has been fully installed and checked for even floor contact.

After installation, cycle the door carefully and verify that the seal does not bind, shift, or interfere with normal operation. Confirm that the bulb-style flap makes consistent contact across the bottom of the opening.

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.
