Frequently Asked Questions
- How do I measure for an accordion boot?
Use a flexible measuring tape to trace the perimeter of the pass-through opening between your cab and camper.
- Is the truck cap rear window seal?srsltid=afmbooqacxf4qikaipdsotbxceeqleqkcz0oojmo0epqtfs87r0navhy reusable if I remove it?
While technically reusable, removal often deforms the material or compromises the embedded clip, so we recommend replacing it if removed.
- 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.
