• Length and Fit: Trim to your needed length for a precise fit along the door edge.

Durability and materials

Constructed from a resilient PU sponge, the weatherstripping is designed to endure temperature changes and daily use, maintaining form and function through seasons of weather exposure. The combination of a robust profile and a snug seal helps keep outdoor elements at bay while preserving interior comfort.
