Truck Blind Spot Window Seals

If your 18-wheeler or truck would benefit from a drivers-side small peeper window, you need a weatherproof, heat- and cold-resistant seal to hold it in place. Trim-Lok’s EPDM locking gasket provides excellent resistance to ozone, sunlight, severe weather conditions, oxygen, acids, and aging, making it an ideal window seal for semi-truck blind spot windows.

Semi-Truck Door Seals & Edge Trims

Plastic Edge Trim

As the product of choice in the automotive and transportation industries, Trim-Lok’s plastic edge trim products make ideal semi-truck door edge finishes. These plastic clips and trim profiles are made of strong material like PVC and require no fancy tools or skills to install. We promise a secure hold, and we offer decorative finishes to match the semi-truck’s design.

Rubber Trim-Seals

Do you need a reliable door seal to protect your 18-wheeler from weather damage with a clean, finished look? Rubber trim-seals are made from flexible PVC plastic trim with an attached EPDM sponge rubber tubing, and they come in bulb sizes ranging from .20 inches to 1 inch with custom fits available. They stay in place through extreme weather and temperatures while providing superior flexibility and easy installation. Learn more about our rubber trim-seals for truck doors.
