Bulb-Type Bottom Weather Seals

This bulb-type bottom weather seal is a replacement weather seal designed for compatible residential and commercial garage doors. It installs in the existing bottom channel and features a rigid upper profile that holds the seal in place. The attachment shape is compatible with specific Overhead Door series and models, as well as other garage doors that use a similarly shaped bottom channel.

Made from black EPDM rubber, the seal combines a flexible sponge bulb with a rigid top. The bulb conforms to uneven surfaces beneath the closed door to help block drafts, dirt, dust, debris, and adverse weather. Choose the per-foot option for a custom continuous length or select a complete 90-foot reel for larger projects and multiple-door installations.

Why Choose This Garage Door Bottom Seal?

Installation Best Practices

This garage door bottom seal slides into a compatible channel along the bottom of the door. Inspect the existing channel before installation because damage, corrosion, or accumulated debris may prevent the replacement seal from feeding smoothly or seating correctly.

• Confirm that the rigid attachment profile matches the existing bottom channel before removing the old seal.
• Measure the garage door opening rather than relying on the old seal, which may have stretched or shrunk over time.
• Clean dirt, rust, and debris from the channel before feeding the replacement seal into place.
• Use a small amount of diluted dish soap as a lubricant if the seal does not slide easily through the channel.
• Have a second person guide and support longer lengths to reduce stretching and binding during installation.
• Center the seal and confirm even contact with the floor before trimming any excess material.

After installation, close the garage door and inspect the full width of the seal. The bulb should make consistent contact with the surface beneath the door without being excessively compressed.

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.

Frequently Asked Questions

How do I know whether this bulb-type garage door bottom seal will fit?

Compare the rigid upper attachment profile with your existing seal and bottom channel. This product is compatible with the listed Overhead Door series and models, but the attachment shape should always be verified before ordering.

Select the per-foot option and enter the total footage needed in the Quantity field. For example, a quantity of 16 orders one continuous 16-foot piece.

Can this garage door bottom seal be trimmed?

Yes. Install and center the seal first, then trim excess material after confirming that it makes even contact across the bottom of the closed garage door.
