Slim-Line Roll Up Garage Door Brush Seal Kit

The Slim-Line Roll Up Garage Door Brush Seal Kit is a complete garage door brush seal kit designed to seal the top and sides of rolling steel, sectional, mini warehouse, commercial, and residential garage doors. Each kit includes durable Slim-Line polypropylene Flex Brush seals, pre-punched aluminum retainers, and 32 mounting fasteners for a complete installation. Available in multiple door sizes, brush lengths, and retainer profiles, this kit provides an effective solution for reducing drafts while helping keep out rain, snow, dust, insects, and debris.

The polypropylene brush filaments resist water absorption, helping prevent freezing and sticking in cold weather while maintaining reliable contact over uneven door surfaces. The slim-line design is ideal when a lower-profile retainer is preferred without sacrificing long-lasting weather protection.

Choosing Your Kit

About Our Cut-Down Kits: Cut-down kits use factory-cut aluminum retainers supplied in 4-ft. 1-in. or 5-ft. 1-in. sections depending on the selected door size. Shipping the retainers in shorter sections reduces shipping costs while making the kit easier to handle and install.

Example: An 8' × 8' cut-down kit includes six 4-ft. 1-in. retainer sections with the brush seals pre-installed.

Frequently Asked Questions

Can this garage door brush seal kit be trimmed?

Yes. The aluminum retainers can be cut with a hacksaw, and the brush seals can be trimmed with scissors to fit your installation.

Which brush size should I choose?

Select a brush length that matches the gap between the door and the building. The brush should lightly contact the door surface without excessive compression.

Why are the aluminum retainers supplied in shorter sections?

To reduce shipping costs and improve handling, many kits include retainers factory cut into 4-ft. 1-in. or 5-ft. 1-in. sections. The brush seals are pre-installed, and the sectional retainers install together to provide the same finished performance as longer lengths.
