Frequently Asked Questions

Our boots are made from high-quality black EPDM rubber, known for its durability, UV resistance, and flexibility across extreme temperatures.
- How long will my between cab and cap truck boot last?
EPDM rubber is extremely durable, UV-resistant, and built to last for years. Proper installation can extend its lifespan significantly.
- Can you make the accordion gasket in different colors?
Sorry the boot only comes in black. We have never tested it, but the rubber is epdm and with the right paint is can be colored. From the research the recommended paint should be an acrylic coating specifically designed for epdm rubber. Usually this is paint for roofing. Latex paint should be avoided.
