Flaps & Corner Sections

Flaps & Corner Sections
Rubber flap seals and corner trim products are generally manufactured with EPDM rubber and provide good sound insulation, shock absorption, UV and ozone resistance, weatherproofing, and have anti-aging qualities. Since they come in a variety of specially designed shapes and are made from a custom formulated EPDM sponge rubber compound, flap trim and rubber corner trim can be used in a variety of applications and environments. With a general temperature rating of -20°F. to 158°F., our corner trim products are ideal for numerous applications.

Perfect for a variety of applications, our rubber corner trim will protect and complement the exterior of your application. They’re ready to install upon delivery and built using only the highest quality materials.. Each rubber corner trim product resists denting, peeling, rusting, flaking, and corrosion — and won’t require the services of a professional to install. With two tape choices, BT and HT, you’ll also find the perfect bond for the intended application.

Typically used for protection against water and dust, rubber flap seals are the perfect sealing option as they’ll remain unaffected by even extreme changes in weather or climate. Whether you live in a dry desert or a snow-filled valley, our flap trim will provide the protection your car or truck needs. Rubber corner trim and flap seals are used in the automotive, construction, and marine industries, in addition to applications that include furniture and glass or aluminum doors and windows.

For over 40 years, Trim-Lok has been providing flap seals and corner sections to the marine, automotive, industrial, and manufacturing industries. While we may specialize in the design, construction, and distribution of rubber seals and rubber seal products, it’s our flexible approach and dedication to quality that truly sets Trim-Lok apart from our competitors.
