Frequently Asked Questions

  • Will the installing truck cap boot work with thin metal or wood frames?

    Yes, but there must be a flange no thicker than 3/16". For wood or thick materials, add a metal strip (like aluminum flat bar) around the opening for the installing truck cap boot to grip.

  • What if I’m not satisfied with my installing truck cap boot?

    We offer a 30-day money-back guarantee. If you're not satisfied, simply contact customer service and return the product.

  • 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.
