Crafted with ultra-strong adhesive tape and premium EPDM foam, this tonneau cover seal strip offers top-tier weather resistance (UV protection, -40°C~120°C), resisting aging and cracking for long-lasting outdoor use on truck beds and RVs. Its marine-grade ribbed structure forms a tight multi-layer seal, blocking moisture, dust, noise and air while absorbing shocks to safeguard your truck components. Ideal for truck tonneau covers, this self-adhesive seal is also multi-functional for RVs, boats, garage doors, meeting all windproof, waterproof and sound insulation needs. With strong adhesive, it enables tool-free installation—simply clean the surface, peel the backing and press for a firm, long-lasting hold that won't peel. Measuring 3/5" (1.2cm) in width, 0.4" (1.0cm) in thickness and 65" (165.1cm) in length, it fits most standard tonneau covers for optimal sealing performance.
