Frequently Asked Questions
- Is the accordion boot waterproof?Yes, when installed correctly, it creates a watertight and dustproof seal between compartments. 
- What if the camper shell opening is larger than my truck window?If the shell opening is larger, the truck cap gasket window may not work. You’ll either need to modify the opening or consider a compression boot instead, which is more forgiving in such situations. 
- Do I need glue to install the accordion boot?The rubber boot does not require glue for installation. It has a spring clip embedded in the rubber. When the boot is placed over a flange, the clip squeezes the rubber securely. The only optional gluing is at the seam using cyanoacrylate (SuperGlue). Avoid petroleum-based adhesives like rubber cement.
