CRL Z78172C 100ft Roll Zipper Pile Weatherstrip, 0.250" Pile Height, 0.187" Backing Width-Gray

CRL Zipper Pile Weatherstrip provides a high-density, water-resistant sealing solution for doors and windows. Its zipper-tooth polypropylene backing allows the pile to snap directly into the extrusion slot from above, eliminating the need to insert it from the ends. This innovative design simplifies installation, making it faster and more convenient for both manufacturing and retrofit applications, even when slot dimensions vary slightly. The weatherstrip is suitable for aluminum, vinyl, fiberglass, and wood T-slot frames without requiring disassembly of the sash. A double center fin creates an effective barrier against air, moisture, and dust, providing a dependable weather seal and improving energy efficiency. Designed for durability and long-term performance, this pile offers consistent sealing quality across a wide range of residential and commercial window or door systems.
