Frequently Asked Questions

  • How long will my truck cab donut last?

    EPDM rubber is extremely durable, UV-resistant, and built to last for years. Proper installation can extend its lifespan significantly.

  • I have a Ford F150 with a LEER top. I an pretty sure the accordion seal is the correct option but the warning that the opening must be an exact match has me concerned. It looks like the truck opening is larger at the lower corners but until the window is removed, who knows? Am I on safe ground getting the accordion seal for this application?

    The accordion boot only stretches one direction. There is a metal clip embedded in the rubber that allow you to attach the boot to the fiberglass/sheet metal, Therefore both window openings must be the same size. If the opening in the shell is smaller you can cut and trim the fiberglass to match the truck's window opening.

  • I have a truck that I want to install a camper shell on. The shell has a slider and I will need to remove the rear cab window. Is there a procedure when using a boot that insures a watertight seal?
