    The Action Industries Tri-Fin Polar Seal is a top of the line, premium product designed for commercial spaces in cold climates. The Tri-Fin Polar Seal is made of the durable rubber EPDM, which performs in a wide range of temperatures from -60 to over 200 degrees Fahrenheit. It’s an excellent seal for colder environments because of how pliable it stays in freezing weather compared to vinyl.

    The seal also performs well in glacial areas because of its superior design. The Tri-Fin Polar Seal has a rubber thermal break that acts as a gasket under the retainer which seals tightly. It also has two fins created specifically for northern work in freezing areas. If one flap is lifted or blown in the wind, the other flap will stay stable. These two flaps also offer double insulation and keep the door well-protected from the cold.

    The Tri-Fin Polar Seal should be used with the Action Industries Standard 45-degree retainer (A0282).

    You can choose to buy seal kits or individual components in 100’ reels.
