CRL E-Lon® Foam Tite® Weatherseal is a compression seal for kerf-fitted wood or metal doors and French Style doors. It efficiently restricts air, light, water, and sound infiltration. Its closed cell foam profile remains flexible through thousands of compressions, while the TPE skin coating provides easy breakaway and ensures long life. The rigid dual-locking barbs fit standard 1/8" x 3/8" (3.2 x 9.5 mm) kerfs, insert easily, and hold securely without slipping.
