Ultra Rubber EPDM Garage Door Bottom Seal Replacement Kit

The Ultra Rubber EPDM Garage Door Bottom Seal Replacement Kit is a complete garage door bottom seal kit designed to replace worn or damaged bottom weather seals on residential and commercial garage doors. Each kit includes a premium EPDM rubber bottom seal, heavy-duty aluminum retainer, mounting screws, and rubber stoppers, providing everything needed for a complete replacement. Available for doors up to 9' or 18' wide, each kit can be trimmed to fit your exact door size.

Unlike standard vinyl seals, this EPDM synthetic rubber seal remains flexible in temperatures down to -50°F, making it an excellent choice for garages exposed to extreme heat, cold, dust, humidity, insects, rodents, and other environmental conditions. The double-walled seal design also helps resist chewing damage from pests while creating a durable seal against uneven floors and air infiltration.

Technical Specifications

Frequently Asked Questions

Will this garage door bottom seal kit fit my garage door?

This replacement kit includes a new aluminum retainer, so your existing bottom retainer does not need to match. Simply choose the retainer option that matches your garage door thickness (1-3/8", 1-3/4", or 2"). The included retainer replaces your existing retainer and uses a 1/4" T-end EPDM bottom seal.

Why choose EPDM instead of a standard vinyl garage door seal?

EPDM synthetic rubber remains flexible in temperatures down to -50°F and offers excellent durability for garages exposed to extreme weather, humidity, pests, and large temperature swings.

Can the kit be cut to fit my garage door?

Yes. Both the 9' and 18' kits are designed to be trimmed to your exact door width. The aluminum retainer can be cut with a handsaw, and the rubber seal can be cut with standard household scissors.

What is included with the replacement kit?

Each kit includes the Ultra EPDM bottom seal, matching aluminum retainer sections, mounting screws, and rubber stoppers for a complete installation.
