Bottom-Mount Overhead-Door Weatherstripping

Close the gap between the bottom of an overhead door and the floor.

Face-mount weatherstripping withstands use on doors that are frequently opened and closed.

Flat seals press against surfaces to create a seal. Neoprene resists abrasion. EPDM resists UV and abrasion.

Bulb seals compress to form a tight seal and can compensate for uneven surfaces. Vinyl is the most economical choice. Neoprene resists abrasion.

Frame-Mount Overhead-Door Weatherstripping

Shown Installed

Flat Seal

Brush Seal

Mount this weatherstripping to the sides and top of an overhead door frame to close gaps. The seals are angled, so they press against the door’s surface without blocking its path.

Flat seals form a solid barrier when used on even surfaces. However, they don’t conform to rough textures or raised trim as much as brush seals do. Made from vinyl, these seals are flexible, durable, and moisture resistant.

Brush seals have flexible bristles that fill gaps in uneven surfaces, so they stop drafts better than flat seals. Made of nylon, they’re strong, long-lasting, and they stand up to UV light and moisture.

Dock Door Draft Seals

Keep drafty dock areas warm. These seals block drafts between dock door seals and levelers. They’re filled with foam, so you can squish them into gaps for a tight seal. The weighted base will keep them in place. Use the handle to pull them out of gaps and carry them.

Self-Aligning Dock Door Shelters

This shelter is spring loaded, allowing it to retract and flex with trailers to provide a better seal than standard dock door shelters. It can also be used to create a seal between oversized door openings and trailers. To mount in block or brick, 3/8" or 1/2" Dia. × 4" Lg. anchors are required.

Dock Door Seals

Close the gap between your dock door and a trailer to keep heated or cooled air in and dust out while loading or unloading. Choose a seal that projects a maximum of 5" beyond your dock bumper. If your dock has an edge-of-dock leveler, order the seal with a 20" projection.

Dock Door Shelters

To provide more protection from the elements than dock door seals, these shelters wrap around trailers. They can also be used to create a seal between oversized door openings and trailers. These shelters include two steel protectors to prevent damage to the shelters and trailers.

Shelters with a 24” projection require 3/8" or 1/2" Dia. × 4" Lg. anchors to mount in a block or brick.
