WRS .450" Pile Height x .187" Backing High Fin Weatherstripping for Windows – White Window Channel Weather Stripping Replacement, Low Friction Seal for Vinyl & Aluminum Windows (24 ft Roll)

This high fin weatherstripping for windows is designed to seal larger gaps in aluminum and vinyl window systems while maintaining smooth operation. Installed in the window channel, it helps reduce drafts, air leaks, and water infiltration. The extended center fin improves sealing performance by creating a stronger barrier against air and moisture compared to standard fin seal designs. Combined with low-friction synthetic pile fibers, it allows windows to open and close easily without resistance. With a .450" pile height and .187" backing width, this weatherstripping is ideal for applications requiring a taller sealing profile and narrower channel fit. Matching the correct size is essential to ensure proper installation and performance. Commonly used in single and double hung windows, as well as casement frames and meeting rails, this product provides a reliable solution for restoring window sealing, insulation, and efficiency. WRS supplies trusted window and door hardware used by professionals, contractors, and maintenance teams for dependable repair and replacement solutions.
